Description

Quick support device Technical Field The utility model relates to the technical field of foundation pit support, in particular to a rapid support device. Background In engineering fields such as mine tunnel, tunnel construction, building foundation pit, temporary support device is crucial to guarantee construction safety. The traditional supporting structure generally adopts a fixed supporting or manually-adjusted jack, a hydraulic prop and the like, and has the technical defects that the adjusting efficiency is low, the traditional supporting device needs to adjust the heights or angles of supporting points one by one, the operation is complex, the surrounding rock deformation or construction requirements are difficult to respond quickly, and the rescue and supporting efficiency is influenced. The stability is insufficient, the single-point support or non-linkage adjustment can cause uneven stress of the support plate, deflection or instability can easily occur, and the risk is aggravated under the action of dynamic load (such as rock mass displacement). The support device has poor adaptability, the support angle of the existing support device has limited adjustment range, and the support device is difficult to adapt to the support requirements under complex geological conditions, such as quick support of an inclined top plate or a local collapse area. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a rapid supporting device, which solves the technical problem that the supporting angle of the supporting device in the prior art is limited. According to the embodiment of the utility model, the following technical scheme is adopted: A quick support device comprising: A base; The support guard board is rotationally arranged on the base; The support piece comprises two telescopic rods and a support rod, the support rod and the support plate are arranged at intervals, and the two telescopic rods are arranged between the support rod and the support plate in a staggered manner along the up-down direction; when the two telescopic rods extend or retract under the action of external force, the telescopic rods are used for linking the support plate to rotate along the base. Preferably, the support plate is provided with a first support lug and a second support lug, the support rod is movably provided with a first sleeve and a second sleeve, two ends of one telescopic rod are respectively connected with the first support lug and the first sleeve, and two ends of the other telescopic rod are respectively connected with the second support lug and the second sleeve. Preferably, the first sleeve and the second sleeve each comprise a first enclosing part and a second enclosing part, and the first enclosing part and the second enclosing part enclose a mounting cavity. Preferably, the first enclosing part and the second enclosing part are outwards provided with a limiting boss in a protruding mode, and the limiting boss is provided with a plurality of bolt holes. Preferably, the base is provided with a plurality of positioning holes for inserting positioning rods, and the positioning rods are perpendicular to the base. Preferably, the base is provided with a containing cavity, and the balancing weight is detachably arranged in the containing cavity. Preferably, a yielding groove is formed between the base and the support plate. Compared with the prior art, the utility model has the following beneficial effects that 1. The utility model has the advantages of quick response, improved supporting efficiency, and the synchronous telescopic movement of the two telescopic rods can directly drive the supporting plate to rotate, does not need to adjust supporting points one by one, obviously shortens the supporting time, and is particularly suitable for emergency supporting or dynamic construction environments. 2. The supporting stability is enhanced, the two telescopic rods are arranged in a vertically staggered mode, so that moment balance is formed, deflection or lateral instability of the supporting plate is prevented when the supporting plate is stressed, and the integral supporting rigidity is improved. 3.
