Description

Drilling device for structural adhesive anchor bars Technical Field The utility model relates to the technical field of drilling devices, in particular to a structural adhesive anchor bar drilling device. Background The structural adhesive anchor bar is a reinforcing technology widely used in building engineering, and mainly adopts high-performance structural adhesive (such as epoxy resin) to anchor reinforcing steel bars (or screw rods) in a concrete base material to form reliable connection so as to achieve the effects of load transmission, reinforcement, and the like. The existing construction process of the structural adhesive anchor bar sequentially comprises drilling holes, cleaning the holes, injecting adhesive and inserting the anchor bar. The structural adhesive anchor bars are deeper in general drilling, so that the drill rod of the drilling device is longer, a worker can grasp the straightness and depth of the drilling by means of drilling experience when holding the drilling device for drilling, and workers with insufficient experience can easily drill askew or shallow or deep. Disclosure of utility model The utility model provides a drilling device, which aims to solve the defects that the existing drilling device is easy to drill askew, deep and shallow, and is difficult to drill askew and easy to control the drilling depth. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a structure is glued anchor bar drilling equipment, which comprises a housin, a motor, speed reducer and drilling rod, motor and speed reducer are all installed in the casing, motor and speed reducer input transmission are connected, drilling rod and speed reducer output can dismantle and be connected, drilling equipment still includes the display, a controller and two laser rangefinders, laser rangefinder fixed connection is in the casing outside, two laser rangefinders and drilling rod triangle-shaped are arranged, laser emission direction and the drilling rod of laser rangefinder are parallel, laser rangefinder and display are connected to the controller, display output range data and drilling rod speed of advancing. Through above-mentioned setting, laser range finder sends laser to the substrate on, maintains the laser position when drilling and can prevent to bore askew, in addition, laser range finder can measure the drilling rod and bore the degree of depth, more easily to accuse drilling rod and bore the degree of depth, in addition, the display can show the drilling rod drilling speed, prevents that the drilling rod from boring the reinforcing bar in the substrate. Further, the casing includes first casing portion and second casing portion, speed reducer and motor are installed respectively in first casing portion and second casing portion, drilling equipment still includes drive assembly, elastic component and direction prevent changeing the subassembly, the motor passes through drive assembly and the input transmission of speed reducer is connected, the elastic component is installed between first casing portion and second casing portion, the direction prevents changeing the subassembly and includes guide bar and uide bushing, fixed connection is in second casing portion around the uide bushing, guide bar one end and first casing portion fixed connection, the uide bushing is run through to the uide bushing, and extend to second casing portion rear side, be provided with the scale mark on the uide bar. Through the arrangement, the propulsion force is conveniently controlled, the drilling stability is improved, and the drilling is further prevented from being askew. Further, the elastic piece is arranged as a spring, the spring is sleeved on the guide rod, the front end of the spring is connected with the first shell part, and the rear end of the spring is connected with the second shell part. Further, the transmission assembly comprises a transmission shaft with a non-circular cross section and a transmission sleeve matched with the transmission shaft, the transmission shaft is slidably connected in the transmission sleeve and connected with the motor, and the transmission sleeve is connected with the input end of the speed reducer. Through the arrangement, the motor can forward convey torque through the transmission shaft and the transmission sleeve, and meanwhile, when the first shell part and the second shell part are close to or far away from each other, the transmission sleeve and the transmission shaft can relatively slide without interference. Further, a heat radiation hole is provided in a side surface of the second housing portion. Through the arrangement, the heat dissipation of the motor is improved. Further, the display is fixedly mounted on the upper side of the rear end of the second housing portion. Through the arrangement, a worker can conveniently check the display.
