Description

Technical Field

[0001] This utility model relates to the field of mobile elevator technology, and specifically to a car top structure applied to mobile elevators. Background Technology

[0002] With the acceleration of urbanization and the increase in high-rise buildings, elevators, as vertical transportation tools, are becoming increasingly important. While traditional fixed elevators are technologically mature, their installation and use present numerous inconveniences in certain special situations, such as temporary buildings, large event venues, and construction sites. Therefore, mobile elevators have emerged. In the elevator shaft structure of mobile elevators, there are shaft structures that achieve overall installation through the splicing of multiple layers of shaft frames. This allows for design based on the height of the mobile cabin, thereby improving flexibility and adjustability, adapting to various changes, increasing installation efficiency, and reducing costs. For a specific example, refer to the splicing method of the guide rail in a mobile villa elevator showroom disclosed in Chinese Utility Model Patent Application No. 202323026788.7.

[0003] However, when this type of modular frame structure is moved, it may be necessary to hoist the car together with the top frame, or to keep the car fixed to the frame while the frame is being hoisted. Therefore, the existing car structure is insufficient in maintaining its fixed function and is prone to sliding, which cannot meet the special usage requirements of mobile elevators. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a car top structure for mobile elevators.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A car top structure for a mobile elevator includes a car body and a car frame. The car body is mounted on the car frame. The car frame includes an upper crossbeam located above the car body. Safety clamp assemblies and positioning assemblies are symmetrically arranged at both ends of the upper crossbeam. A linkage assembly is also provided between the safety clamp assembly and the positioning assembly on the same side. When the positioning assembly is activated, the linkage assembly can drive the safety clamp assembly to move synchronously. The safety clamp assembly includes a fixed clamp seat fixed at the end face of the upper crossbeam, a movable clamp movably engaged with the fixed clamp seat, a connecting rod rotatably engaged with the upper crossbeam, and a crank arm connecting the movable clamp and the connecting rod. When the connecting rod rotates, it drives the movable clamp to move on the fixed clamp seat through the crank arm. The positioning assembly includes a positioning seat fixed on one side of the upper crossbeam, a movable pin movably mounted on the positioning seat, and a positioning plate fixed on a guide rail. One end of the movable pin is engaged with the positioning seat, and the other end extends towards the positioning plate. The positioning plate has a positioning hole, and the movable pin is engaged in the positioning hole to form a limit.

[0007] In this utility model, the linkage component includes a linkage rod that slides on the upper crossbeam and a rack disposed on the linkage rod. One end of the linkage rod engages with a movable pin through the rack, and the other end engages with a connecting rod through the rack.

[0008] Furthermore, the outer surface of the movable pin is provided with a toothed structure, which cooperates with the rack. The connecting rod is provided with a driven gear, which cooperates with the rack. When the movable pin is rotated downward, the movable pin drives the linkage rod to move upward through the toothed structure, and the other end of the linkage rod drives the driven gear to rotate through the rack, thereby driving the connecting rod to rotate.

[0009] In this utility model, the linkage assembly further includes two sliding blocks, which are symmetrically fixed on both sides of the upper crossbeam, and the two ends of the linkage rod slide and engage with the two sliding blocks from top to bottom.

[0010] In this invention, the two ends of the upper crossbeam extend downwards in a vertical direction as side beams. These two side beams are located on both sides of the car body, and their bottom ends are connected to support frames. The car body is mounted on the support frames. Both the upper and lower ends of the side beams on both sides are provided with guide shoes that slide in cooperation with the guide rails. The car frame slides up and down along the guide rails via the guide shoes, thereby driving the car body to move up and down.

[0011] In this invention, the safety clamp assemblies at both ends are linked by a connecting rod to achieve synchronous action. The connecting rod is rotatably mounted on the side of the upper crossbeam away from the positioning assembly. One end of the crank arm is fixedly connected to the end of the connecting rod, and the other end is hinged to the bottom of the movable clamp. When the connecting rod rotates, the crank arm pushes the movable clamp to move up or down.

[0012] Furthermore, the fixed clamp seat is provided with a clamping channel, and a fixed clamp is provided on one side of the clamping channel. The movable clamp is movably engaged on the other side of the clamping channel. The movable clamp and the fixed clamp seat are slidably engaged by an inclined plane. When the movable clamp moves upward, the relative distance between the movable clamp and the fixed clamp gradually decreases, and vice versa.

[0013] In this utility model, a drive handle is connected to the movable pin, the drive handle extends radially outward along the movable pin, the positioning seat is provided with a locking structure, the drive handle cooperates in the locking structure to form a limit, and the end of the drive handle is also provided with a gravity ball to make the drive handle hang down naturally.

[0014] Furthermore, the positioning plate is provided in multiple pieces, and the multiple positioning plates are arranged and installed along the guide rail.

[0015] This utility model has the following advantages and beneficial effects:

[0016] By installing a safety clamp assembly and a positioning assembly on the car frame above the car body, the safety clamp assembly and the positioning assembly on the same side are driven synchronously through a linkage assembly. When it is necessary to keep the car fixed, the movable pin can be inserted into the positioning plate through the positioning assembly to form a limit. Then, the movable pin drives the safety clamp assembly to clamp the guide rail through the linkage rod, thus forming a double protection and ensuring the stability and reliability of the car when it is fixed.

[0027] like Figures 1 to 6As shown, this embodiment discloses a car top structure for a mobile elevator, including a car body 1 and a car frame 2. The car frame 2 includes an upper crossbeam 21 located above the car body 1. Side beams 22 extend vertically downwards from both ends of the upper crossbeam 21. The two side beams 22 are located on both sides of the car body 1, and a support frame 23 is connected to the bottom end of each side beam 22. The car body 1 is mounted on the support frame 23. Guide shoes 24 that slide in cooperation with guide rails 3 are provided at both the upper and lower ends of the side beams 22. The car frame 2 slides up and down along the guide rails 3 via the guide shoes 24, thereby driving the car body 1 to move up and down. Specifically, the upper crossbeam 2... At both ends of 1, there are symmetrically arranged safety clamp assemblies 25 that clamp the guide rail 3 to prevent slippage in an emergency, and positioning assemblies 26 that position the car frame 2 on the guide rail 3. A linkage assembly 27 is also provided between the safety clamp assembly 25 and the positioning assembly 26 on the same side. When the positioning assembly 26 is activated, it can drive the safety clamp assembly 25 to move synchronously through the linkage assembly 27. The safety clamp assembly 25 includes a fixed clamp seat 251 fixed at the end face of the upper crossbeam 21, a movable clamp 252 movably engaged with the fixed clamp seat 251, a connecting rod 253 rotatably engaged with the upper crossbeam 21, and a crank arm 254 connecting the movable clamp 252 and the connecting rod 253. When 253 rotates, the crank arm 254 drives the movable clamp 252 to move on the fixed clamp seat 251, thereby clamping the guide rail 3; the positioning component 26 includes a positioning seat 261 fixed on one side of the upper crossbeam 21, a movable pin 262 movably mounted on the positioning seat 261, and a positioning plate 263 fixed on the guide rail 3. One end of the movable pin 262 is engaged with the positioning seat 261, and the other end extends towards the positioning plate 263. The positioning plate 263 is provided with a positioning hole. Pushing the movable pin 262 axially causes it to engage in the positioning hole to form a limit, thereby fixing the car frame 2 on the guide rail 3; the linkage component 27 includes a linkage rod 271 slidably engaged with the upper crossbeam 21 and a positioning plate 263 fixed on the guide rail 3. A rack 272 is mounted on the linkage rod 271. One end of the linkage rod 271 engages with a movable pin 262 via the rack 272, and the other end engages with a connecting rod 253 via the rack 272. Specifically, a toothed structure 274 is provided on the outer surface of the movable pin 262, which engages with the rack 272. In addition, a driven gear 273 is provided on the connecting rod 253, which engages with the rack 272. When the movable pin 262 is rotated downwards, the linkage rod 271 is moved upwards through the toothed structure 274, while the other end of the linkage rod 271 drives the driven gear 273 to rotate via the rack 272, thereby driving the connecting rod 253 to rotate. When it is necessary to keep the car fixed, the movable pin 262 can be engaged into the positioning plate 263 by the positioning component 26 to form a limit, and then the safety clamp component 25 can be driven by the movable pin 262 to clamp the guide rail 3, thus forming a double guarantee to ensure the stability and reliability of the car when it is fixed.

[0028] In this embodiment, the linkage assembly 27 further includes two sliding seats 275, which are symmetrically fixed on both sides of the upper cross beam 21. The linkage rod 271 has a "C" - shaped structure, and both ends of the linkage rod 271 are slidably engaged with the two sliding seats 275 from top to bottom.

[0029] In this embodiment, the safety clamp assemblies 25 at both ends are linked to achieve synchronous movement through a connecting rod 253. Specifically, the same connecting rod 253 is used for connection. The connecting rod 253 is rotatably installed on one side of the upper cross beam 21 far from the positioning assembly 26. One end of the crank arm 254 is fixedly connected to the end of the connecting rod 253, and the other end is hinged to the bottom of the movable clamp 252. When the connecting rod 253 rotates, it pushes the movable clamp 252 to move up or down through the crank arm 254. Specifically, a clamping channel 255 is provided on the fixed clamp seat 251, a fixed clamp 256 is provided on one side of the clamping channel 255, and the movable clamp 252 is movably engaged on the other side of the clamping channel 255. In addition, the movable clamp 252 and the fixed clamp seat 251 are slidably engaged through an inclined plane. When the movable clamp 252 moves upward, the relative distance between the movable clamp 252 and the fixed clamp 256 gradually decreases, thereby clamping the guide rail 3.

[0030] In this embodiment, in order to keep the movable pin 262 in an extended state or a contracted state, a driving handle 264 is connected to the movable pin 262. The driving handle 264 extends radially outward along the movable pin 262. Specifically, a threaded hole is machined radially on the movable pin 262, and one end of the driving handle 264 is threadedly engaged in the threaded hole. In addition, a "I" - shaped clamping structure 265 is provided on the positioning seat 261, and the driving handle 264 is engaged in the clamping structure 265 to form a limit. It should be noted that the "I" - shaped clamping structure 265 is horizontally arranged, and the movable pin 262 is clamped in the clamping positions at both ends in the extended or contracted state. When the movable pin 262 needs to be moved, the driving handle 264 is moved to the other end along the middle of the clamping structure 265. At the same time, a gravity ball is provided at the end of the driving handle 264 to make the driving handle 264 droop in the natural state.

[0031] Furthermore, in order to enable the car body 1 to stay at different track heights, multiple positioning plates 263 are provided. The multiple positioning plates are arranged and installed along the guide rail 3, so as to position the car frame 2 at different heights.

[0032] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
