Description

Technical Field

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

[0002] Mobile elevators, as temporary or semi-permanent vertical transportation equipment, are widely used in construction sites, large event venues, temporary facilities, and other occasions. Unlike traditional fixed elevators, mobile elevators need to be able to be quickly installed, disassembled, and moved; therefore, their frame structure design needs to balance portability and stability.

[0003] During the operation of a mobile elevator, the stability of the hoist frame directly affects the elevator's safety and reliability. Since mobile elevators frequently need to be installed and disassembled in different locations, the locking and positioning structure of the hoist frame is particularly important. Traditional locking and positioning structures often use bolt connections or pin fixation (see the connection method between the support legs and support blocks in a mobile villa elevator exhibition hall disclosed in Chinese Utility Model Patent Application No. 202323026788.7). While these methods are simple, they are prone to wear and loosening during frequent disassembly and installation, affecting the safe operation of the elevator. Furthermore, traditional locking and positioning structures require significant manpower and time during installation and disassembly, increasing construction and time costs. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a locking and positioning structure for use in mobile elevators.

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

[0006] A locking and positioning structure for a mobile elevator includes two opposing positioning blocks and a support block. The positioning blocks are fixed to the bottom of the upper hoist frame, and the support block is fixed to the top of the lower hoist frame. The bottom of the positioning blocks is horizontally arranged to form a positioning surface, and the top of the support blocks is horizontally arranged to form a support surface. The positioning surface has a positioning groove, and the support surface has a positioning protrusion. The positioning protrusion corresponds to the positioning groove. The positioning blocks also have a locking buckle, and the support blocks also have a locking groove for engaging with the locking buckle. The upper part of the locking buckle is hinged to the positioning block, and the lower part of the locking buckle has a hook-like structure. The positioning blocks abut against the support blocks to form support. The positioning groove on the positioning blocks is embedded in the positioning protrusion to form a limit, and the hook-like structure on the locking buckle is engaged in the locking groove to form a vertical limit.

[0007] In this utility model, the locking buckle is a plate-shaped structure, the hook-shaped structure is located on the inner side of the bottom end of the locking buckle, and the top end of the locking buckle is also provided with a hinge part. The hinge part is provided with a hinge shaft, and the hinge part is offset towards the inner side of the locking buckle, so that the hinge shaft is away from the center of gravity of the locking buckle.

[0008] Furthermore, the locking buckle has a protrusion extending outward from one end of the hook-shaped structure, and the protrusion forms an angle with the hook-shaped structure.

[0009] Furthermore, a locking plate is provided on the positioning block above the locking buckle. The upper part of the locking plate is hinged to the positioning block via a pivot. A torsion spring is also provided on the upper part of the locking plate at the pivot. The torsion spring drives the locking plate to deflect downward. A snap-fit ​​structure is provided at the end of the locking plate away from the pivot. A slot is provided on the end of the locking buckle near the hook-shaped structure to engage with the snap-fit ​​structure. The snap-fit ​​structure engages in the slot to limit the locking buckle.

[0010] Furthermore, the inner side of the locking plate is provided with a limiting part, and a limiting stop is provided at one end of the locking buckle located at the hinge part. When the locking buckle is engaged in the locking groove, the locking plate abuts against the limiting stop through the limiting part to form a limiting position.

[0011] In this utility model, both the upper and lower derricks include four vertically arranged support angle steels and multiple horizontally arranged support side plates. The multiple support side plates are connected between two adjacent support angle steels to form a three-sided enclosed structure. The top of the upper derrick is connected by connecting beams to form a rectangular top frame, and the bottom of the lower derrick is connected by connecting beams to form a rectangular bottom frame. The positioning block is fixed on the outside of the bottom of the support angle steel on the upper derrick, and the support block is fixed on the outside of the top of the support angle steel on the lower derrick. Each of the four support angle steels on the upper derrick is provided with a positioning block, and each of the four support angle steels on the lower derrick is provided with a support block.

[0012] In this utility model, a number of intermediate derricks are provided between the upper derrick and the lower derrick. The intermediate derricks are provided with the support block at the top of the supporting angle steel and the positioning block at the bottom of the supporting angle steel.

[0013] This utility model has the following advantages and beneficial effects:

[0014] A positioning block is installed at the bottom of the supporting angle steel on the upper derrick, and a support block is installed at the top of the supporting angle steel on the lower derrick. A positioning groove is provided on the positioning surface at the bottom of the positioning block, and a positioning protrusion is provided on the support surface at the top of the support block. The positioning groove and the positioning protrusion can be used for quick positioning. A locking buckle is also provided on the positioning block, and a locking groove is provided on the support block. The derrick can be quickly installed and disassembled by the locking buckle engaging with the locking groove, thereby reducing manpower and material resources and lowering installation costs.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0025] like Figures 1 to 6 As shown, this embodiment discloses a locking and positioning structure for a mobile elevator, including an upper hoist 1 and a lower hoist 2. The bottom of the lower hoist 2 is fixed in the mobile cabin, and the bottom of the upper hoist 1 is spliced ​​to the top of the lower hoist 2. The locking and positioning structure 3 is disposed at the splice between the upper hoist 1 and the lower hoist 2. Specifically, the locking and positioning structure 3 includes a set of positioning blocks 31 and support blocks 32 arranged opposite to each other. The positioning blocks 31 are fixed to the bottom of the upper hoist 1, and the support blocks 32 are fixed to the top of the lower hoist 2. The bottom of the positioning blocks 31 is horizontally arranged to form a positioning surface 310, and the top of the support blocks 32 is horizontally arranged to form a support surface 320. The positioning surface 310 is provided with a cross-shaped positioning groove 311, and the support surface 32... The upper derrick 1 and the lower derrick 2 are joined together. The upper derrick 1 is supported by the lower derrick 2. The positioning protrusion 321 is provided in a cross shape and the positioning protrusion 321 is positioned in a corresponding position to the positioning groove 311. Specifically, the positioning block 31 is also provided with a locking buckle 33 and the support block 32 is provided with a locking groove 322 for engaging with the locking buckle 33. The upper part of the locking buckle 33 is hinged to the positioning block 31 by a hinge shaft 331. The lower part of the locking buckle 33 is provided with a hook-shaped structure 332. When the upper derrick 1 and the lower derrick 2 are joined together, the positioning block 31 abuts against the support block 32 to form support. The positioning groove 311 on the positioning block 31 is embedded in the positioning protrusion 321 to form a limit in the water direction. The hook-shaped structure 332 on the locking buckle 33 is engaged in the locking groove 322 to form a vertical limit. Positioning can be achieved quickly through the positioning groove 311 and positioning protrusion 321, and quick installation and disassembly can be achieved through the locking buckle 33 hinged to the positioning block 31, reducing manpower and material resources and lowering costs.

[0026] In this embodiment, the locking buckle 33 is a plate-shaped structure, the hook-shaped structure 332 is located on the inner side of the bottom end of the locking buckle 33, and the top end of the locking buckle 33 is also provided with a hinge portion 333. The hinge shaft 331 is disposed on the hinge portion 333. In this structure, the hinge portion 333 is offset towards the inner side of the locking buckle 33, thereby causing the hinge shaft 331 to move away from the center of gravity of the locking buckle 33. When the locking buckle 33 is hinged on the positioning block 31, the eccentric effect of the locking buckle 33 will cause the bottom end to deflect inward, thereby driving the hook-shaped structure 332 to engage in the locking groove 322, thereby preventing the locking buckle 33 from arbitrarily disengaging from the locking groove 322.

[0027] Furthermore, when the derrick needs to be disassembled, the locking buckle 33 needs to be manually rotated outward to disengage the hook-shaped structure 332 from the locking groove 322. To facilitate operation, a protrusion 334 extends outward from one end of the hook-shaped structure 332 on the locking buckle 33. The protrusion 334 forms an angle with the hook-shaped structure 332. During operation, the operator can quickly engage the lock by pulling the protrusion 334 outward.

[0028] Furthermore, when splicing the upper derrick 1 and the lower derrick 2, it is also necessary to keep the locking buckle 33 in a disengaged state. Therefore, a locking plate 34 is provided on the positioning block 31 above the locking buckle 33. The upper part of the locking plate 34 is hinged to the positioning block 31 via a pivot. A torsion spring 341 is also provided on the upper part of the locking plate 34 at the pivot. The torsion spring 341 drives the locking plate 34 to deflect downward. Specifically, a buckle structure 342 is provided on the end of the locking plate 34 away from the pivot. The locking buckle 33 is near the hook-shaped structure 3. One end of 32 is provided with a slot 335 for engaging with the latching structure 342. After the locking buckle 33 is disengaged from the locking slot 322, it continues to rotate upward, causing the latching structure 342 to engage in the slot 335 to form a limit. Thus, the downwardly deflected locking plate 34 can keep the locking buckle 33 in an outward-facing state through the latching structure 342. After the positioning block 31 and the support block 32 are paired, simply lift the locking plate 34 to disengage the latching structure 342 from the slot 335, and the locking buckle 33 can rotate downward and re-engage in the locking slot 322 to form a lock.

[0029] Furthermore, in the hoistway assembly state, to prevent the locking buckle 33 from disengaging from the locking groove 322 due to other unexpected factors, a limiting part 343 is provided on the inner side of the locking plate 34. Correspondingly, a limiting stop 336 is provided at one end of the locking buckle 33 located at the hinge part 333. When the locking buckle 33 is normally engaged in the locking groove 322, the locking plate 34 abuts against the limiting stop 336 through the limiting part 343 to prevent the locking buckle 33 from flipping outward. It should be noted that when the locking buckle 33 flips outward, the direction of the force exerted on the limiting part 343 by the limiting stop 336 is parallel to the locking plate 34, thereby achieving an effective limiting effect. Combined with the rotational deflection force of the torsion spring 341, the limiting part 343 can be driven to always abut against the limiting stop 336, preventing the locking buckle 33 from flipping outward and disengaging from the locking groove 322 due to vibration or other unexpected factors.

[0030] In this embodiment, the upper derrick 1 and the lower derrick 2 have basically the same structure, both including four vertically arranged support angle steels 121 and multiple horizontally arranged support side plates 122. The multiple support side plates 122 are connected between two adjacent support angle steels 121 to form a three-sided enclosed structure. Specifically, the multiple support side plates 122 are respectively connected to two support angle steels 121 located on the left, right and rear sides. At the same time, the top of the upper derrick 1 is connected by a connecting beam 123. A rectangular top frame is formed, and the bottom of the lower derrick 2 is connected by a connecting beam 123 to form a rectangular bottom frame. The positioning block 31 is fixed to the outside of the bottom of the supporting angle steel 121 on the upper derrick 1, and the support block 32 is fixed to the outside of the top of the supporting angle steel 121 on the lower derrick 2. It should be emphasized that each of the four supporting angle steels 121 on the upper derrick 1 is equipped with a positioning block 31, and each of the four supporting angle steels 121 on the lower derrick 2 is equipped with a support block 32, thereby forming a stable four-point connection.

[0031] In this embodiment, when the mobile cabin has multiple layers, the height requirements of the mobile cabin may not be met by splicing the upper derrick 1 and the lower derrick 2. Therefore, several middle derricks 4 are provided between the upper derrick 1 and the lower derrick 2. The structure of the middle derrick 4 is basically the same as that of the upper derrick 1 and the lower derrick 2. Both are formed by connecting the supporting angle steel 121, the supporting side plate 122 and the connecting rod to form a three-sided enclosed frame structure. The difference is that the middle derrick 4 does not have a top frame at the top and a bottom frame at the bottom. The supporting block 32 is provided on the top of the supporting angle steel 121 of the middle derrick 4, and the positioning block 31 is provided on the bottom of the supporting angle steel 121. Multiple middle derricks 4 can be spliced ​​sequentially between the upper derrick 1 and the middle derrick 4 to meet the height requirements of the mobile cabin.

[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.
