Description

Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a support frame used for returning the foundation of an elevator. Background Art

[0002] The elevator foundation top-up is a temporary support facility used to ensure the structural stability of the elevator during installation. It ensures the safety and stability of the construction. When carrying out the elevator foundation top-up construction, it is necessary to comprehensively consider various factors and select the most appropriate top-up solution.

[0003] The support frame of the elevator foundation return is an important structure used to ensure construction safety. It can effectively transfer the load in the elevator shaft to the structure of the building.

[0004] During the installation of the construction elevator, due to the heavy load of the elevator, it is necessary to return the top to the next floor where the foundation floor is located, so as to transfer the weight of the elevator and the goods to the bottom plate, thereby protecting the floor plate. Traditional return top often uses steel pipe scaffolding or pan mouth rack, which is time-consuming and labor-intensive, and requires long-term material rental fees. In addition, the rack occupies too much space, affecting on-site construction. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a support frame for the elevator foundation return to the top. Through the setting of the telescopic keel, the support can be adjusted according to the length of the elevator foundation structure. At the same time, through the insertion and cooperation of the pin with the adjustment hole and the fixing hole, the extension height of the support can be adjusted according to the height of the elevator foundation structure. Thereby, the utility model can be adjusted accordingly according to the length and height of the elevator foundation structure, thereby improving the practicality of the utility model. The overall structure is easy to install and has a low space occupancy rate, so as to solve the problems arising from the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support frame for returning the foundation of an elevator to the top, comprising two groups of support components for returning the foundation structure of an elevator to the top;

[0007] Each support assembly includes two support members with bottom steel plates installed at the bottom, and a plurality of adjustment holes are provided at intervals through the bottom of the support member, a fixing member is provided on the outside of the bottom of the support member, and a plurality of fixing holes corresponding to the adjustment holes are provided on both sides of the top of the fixing member;

[0008] A latch is provided on one side of the top of the fixing member, and one end of the latch passes through the fixing hole and the adjustment hole in sequence and extends to the outside of the fixing member;

[0009] The tops of the two support members are provided with a same telescopic keel, and the top ends of the support members are provided with a top steel plate for connecting the telescopic keel.

[0010] In a preferred embodiment, a common connecting cross bar is provided on one side of the two fixing members, and both ends of the connecting cross bar are respectively fixed to the two fixing members. By setting the connecting cross bar, the stability of the two fixing members can be enhanced, thereby ensuring the supporting strength of the fixing members.

[0011] In a preferred embodiment, a positioning piece is provided at the bottom of one end of the latch, the top of the positioning piece passes through the latch and extends to the top of the latch, a pressure plate is provided on the outside of the positioning piece, and a spring is provided on the bottom of the pressure plate and is sleeved on the outside of the positioning piece. The positioning piece connected to the pressure plate is pushed into the interior of the latch by the rebound force of the spring, and then the positioning piece and the latch are interlaced and connected, so that the positioning piece can fix and limit the latch, thereby ensuring the stability of the latch and avoiding the situation where the support piece loosens due to the separation of the latch.

[0012] In a preferred embodiment, a limit member is provided on the side where the pressure plate and the spring are away from each other. The limit member is sleeved on the outside of the positioning member, and the limit member is installed on the side of the fixing member close to the positioning member. Through the setting of the two limit members, the spring can be easily supported and fixed, and the extreme movement distance of the positioning member can be limited, thereby ensuring the movement stability of the spring and the positioning member.

[0013] In a preferred embodiment, a pedal is installed on the side of the bottom end of the positioning member away from the fixing member. Through the connection between the pedal and the positioning member, the staff can operate the height of the positioning member by stepping on the pedal, thereby improving the convenience of the staff in adjusting the positioning member.

[0014] In a preferred embodiment, the width of the pressure plate is greater than the outer diameter of the spring. By setting the width of the pressure plate to be greater than the outer diameter of the spring, the pressure plate can completely squeeze the spring, thereby ensuring the stability of the fit between the pressure plate and the spring.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting the telescopic keel, the support can be adjusted according to the length of the elevator foundation structure. At the same time, by interlacing and matching the latch with the adjustment hole and the fixing hole, the extension height of the support can be adjusted according to the height of the elevator foundation structure. Thus, the utility model can be adjusted accordingly according to the length and height of the elevator foundation structure, thereby improving the practicality of the utility model. The overall structure is easy to install and has a low space occupancy rate.

[0017] 2. The spring's rebound force is used to push the positioning piece connected to the pressure plate into the interior of the latch. Then, by means of the interlaced connection between the positioning piece and the latch, the positioning piece can fix the latch and ensure the stability of the latch, thus avoiding the situation in which the support part becomes loose due to the separation of the latch.
