Description

Technical Field

[0001] This utility model belongs to the field of elevator maintenance technology, specifically relating to an elevator maintenance rack bracket. Background Technology

[0002] In the routine maintenance and repair of elevators, some maintenance projects require maintenance personnel to enter the elevator shaft to carry out construction operations. Currently, the common method used on-site is to fix a maintenance frame in a pre-drilled hole in the shaft wall to provide a working platform for maintenance personnel.

[0003] However, this traditional fixing method is inefficient. Maintenance personnel must perform complex installation steps within the shaft, including precisely locating pre-drilled holes and fixing various components of the maintenance frame, consuming significant time and effort and severely impacting maintenance efficiency. This inefficient approach can lead to delays, especially during emergency repairs, causing considerable inconvenience to the elevator's normal operation. Furthermore, it lacks stability. Due to potential deviations in the size and location of pre-drilled holes in the shaft wall, as well as factors affecting the wall's strength, the maintenance frame is prone to wobbling and displacement after fixing. This fails to provide a reliable and stable working environment for maintenance personnel, significantly increasing safety risks during the maintenance process. Summary of the Invention

[0004] The purpose of this utility model is to provide an elevator maintenance rack bracket to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An elevator maintenance rack includes a support frame, a base plate fixed to the bottom of the support frame, a crossbar fixed to the upper side of the support frame, threaded rods rotatably mounted on both the left and right ends of the crossbar, a support plate rotatably mounted on the rear side of the threaded rod, a handle fixed to the front side of the threaded rod, a traveling wheel mounted on the lower side of the base plate, and a handle fixed to the front side of the crossbar.

[0006] The crossbar includes two support arms that are hinged to it and are symmetrically distributed on the left and right sides of the crossbar. The lead screw is threadedly connected to the support arm.

[0007] Rubber pads are fixed to the rear side of the support plate and the side of the support frame.

[0008] A guide strip is fixed to the upper edge of the base plate.

[0009] A foot pedal is horizontally fixed in the middle of the support frame.

[0010] The base plate has a square hole in the middle, and a mesh strip is provided in the middle of the square hole. The support frame and the upper side of the cross frame both have triangular hollow holes.

[0011] This mounting bracket, through the cooperation of its support frame, crossbar, and base plate, allows for direct insertion into the elevator shaft after the landing door is opened, enabling quick and easy securing and improving elevator maintenance efficiency. The crossbar's placement against the walls on either side of the landing door ensures a more stable and reliable working environment for maintenance personnel. Turning the handle allows the screw to drive the support plate forward and backward via threaded transmission, better matching wall thickness and enhancing the bracket's versatility. The combination of wheels and a handle allows a single person to easily push the bracket to the target floor elevator entrance, reducing the labor intensity of maintenance personnel when moving the elevator and improving its ease of use. The hinged support arm further enhances the bracket's stability. When not in use, it can be folded inwards to reduce the overall length and volume of the frame, making it easier to transport and store. The rubber pads not only provide anti-slip and shock absorption but also protect the wall. The guide strips allow workers to sense the edge of the base plate by touch when working on the upper side, preventing them from stepping on the edge. The foot pedals facilitate workers' descent to the upper side of the base plate and their climb out of the elevator shaft from the upper side of the base plate, improving the safety of the frame. The mesh strips and triangular perforations ensure the overall structural strength of the frame while making it lighter, further reducing the labor involved in using and transporting the frame and improving its ease of operation.

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, an elevator maintenance rack includes a support frame 101, a base plate 102 fixed to the bottom of the support frame 101, a crossbar 103 fixed to the upper side of the support frame 101, threaded rods 104 rotatably installed at both ends of the crossbar 103, a support plate 105 rotatably installed at the rear side of the threaded rods 104, a handle 106 fixed to the front side of the threaded rods 104, a traveling wheel 108 installed on the lower side of the base plate 102, and a handle 106 fixed to the front side of the crossbar 103.

[0018] When using this bracket, push the entire bracket to the elevator entrance of the part that needs maintenance, then open the landing door of the corridor and push the entire bracket into the elevator shaft. At this time, the left and right ends of the horizontal frame 103 are secured to the walls on the left and right sides of the landing door by the support plate 105, so the bracket is fixed and the staff can stand on the base plate 102 to carry out maintenance work.

[0019] The bracket, through the cooperation of the support frame 101, the crossbar 103, and the base plate 102, allows the bracket to be directly pushed into the elevator shaft after the landing door is opened, thus enabling a quick locking action and improving elevator maintenance efficiency. Simultaneously, the crossbar 103's locking against the walls on both sides of the elevator shaft landing door ensures a more stable overall fixation of the bracket, providing a reliable and stable working environment for maintenance personnel. Turning the handle 106 allows the lead screw 104 to drive the support plate 105 back and forth via threaded transmission, better matching the wall thickness and improving the bracket's applicability. The combination of the traveling wheels 108 and the handle 106 allows a single person to easily push the bracket to the target floor elevator entrance, reducing the labor intensity of maintenance personnel when moving the elevator and improving its ease of use.

[0020] The cross frame 103 includes two support arms 201 that are hinged to it. The support arms 201 are symmetrically distributed on the left and right sides of the cross frame 103, and the lead screw 104 is threadedly connected to the support arms 201.

[0021] The hinged support arm 201 allows the rack to be folded inward when not in use, reducing the overall length and volume of the crossbar 103, thus facilitating the transport and storage of the rack.

[0022] Rubber pads 301 are fixed to the rear side of the support plate 105 and the side of the support frame 101.

[0023] A guide strip 401 is fixed to the upper edge of the base plate 102.

[0024] A foot pedal 501 is horizontally fixed in the middle of the support frame 101.

[0025] A square hole is provided in the middle of the base plate 102, and a mesh strip 601 is provided in the middle of the square hole. Triangular hollow holes 602 are provided on the upper side of the support frame 101 and the cross frame.

[0026] The rubber pad 301 not only provides anti-slip and shock absorption but also protects the wall. The guide strip 401 allows workers to sense the edge of the base plate 102 by touch when working on the upper side of the base plate 102, thus preventing them from stepping on the edge of the base plate 102. The foot pedal 501 facilitates workers to descend to the upper side of the base plate 102 and to climb out of the elevator shaft from the upper side of the base plate 102, improving the safety of the hanger. The mesh strip 601 and the triangular hollow holes 602 ensure the overall structural strength of the hanger while also making the hanger lighter, thereby further reducing the labor required for use and handling and further improving the ease of operation of the hanger.
