Description

Technical Field

[0001] This utility model relates to the field of elevator installation technology, specifically to a positioning tool for elevator hall door sills. Background Technology

[0002] In elevator systems, the distance between the landing sill and the car sill is a core parameter concerning passenger safety. A reasonable distance effectively prevents clothing and limbs from being caught in the elevator shaft and avoids accidents caused by foreign objects falling into the shaft, making it a crucial guarantee for safe elevator operation. According to the "Safety Code for Elevator Manufacturing and Installation," the maximum distance between the landing sill and the car sill must not exceed 35mm.

[0003] Currently, the distance between the hall door sill and the car door sill is mainly determined manually. Installers need to use tools such as levels and steel tape measures to repeatedly measure in the shaft. This method is not only cumbersome and time-consuming, but also susceptible to human error; different operators can easily introduce measurement errors, reducing accuracy. Furthermore, for high-rise buildings, this process needs to be repeated on each floor, resulting in extremely low installation efficiency and making it difficult to guarantee the consistency and accuracy of the sill distance installation.

[0004] Therefore, there is an urgent need to develop a high-precision and high-efficiency positioning tool to solve the problem that the current elevator hall door sills can only be installed by manual measurement and positioning, resulting in low installation accuracy and long installation time. Utility Model Content

[0005] Based on this, and in response to the above problems, this utility model proposes an elevator hall door sill positioning fixture, which solves the problem that currently, elevator hall door sills can only be positioned manually during installation, resulting in low installation accuracy and long installation time.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example:

[0037] like Figures 1 to 3 As shown, this embodiment discloses an elevator hall door sill positioning fixture, including a pair of positioning components 10. The positioning component 10 includes a mounting base plate 100, an adjusting plate 101, and a positioning plate 102. A positioning block 103 is provided on one side of the mounting base plate 100. The adjusting plate 101 is disposed on the other side of the mounting base plate 100 and is rotatably connected to the mounting base plate 100 through a connecting structure 104. The positioning plate 102 is disposed on the adjusting plate 101 and is slidably connected to the adjusting plate 101.

[0038] In use, the mounting base plate 100 of each pair of positioning components 10 is placed on the car door sill, and the positioning block 103 on the mounting base plate 100 is placed in the groove of the car door sill. Then, the adjusting plate 101 is flipped over to extend outside the elevator car. The position of the positioning plate 102 is then adjusted so that one side of the positioning plate 102 is aligned with one side of the car door sill, and the other side of the positioning plate 102 corresponds to the side of the hall door sill closest to the car door sill. When it is necessary to continue installing the hall door sill of the next floor, the adjusting plate 101 is flipped over to be inside the car, and installation can proceed to the next floor. This solves the problem of low installation accuracy and long installation time caused by the current reliance on manual measurement and positioning for elevator hall door sill installation.

[0039] It should be noted that, since this utility model determines the distance between the hall door sill and the car door sill by measuring the width of the positioning plate 102, the width of the positioning plate 102 must meet the requirements for the distance between the hall door sill and the car door sill in the "Safety Code for Elevator Manufacturing and Installation".

[0040] To facilitate the flipping of the adjustment plate 101, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the connecting structure 104 is a hinge, one end of the hinge is fixedly connected to the mounting base plate 100, and one end of the adjustment plate 101 is fixedly connected to the other end of the hinge.

[0041] The hinge can be any existing hinge that can achieve the functions of this utility model. The hinge enables the flipping function of the adjustment plate 101.

[0042] To facilitate the adjustment of the positioning plate 102 and adapt to car door sills of different widths, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the adjustment plate 101 is provided with at least one sliding groove 105, which passes through the adjustment plate 101. The positioning plate 102 is provided with a sliding structure 106 that cooperates with the sliding groove 105. The positioning plate 102 is slidably connected to the sliding groove 105 on the adjustment plate 101 through the sliding structure 106.

[0043] The positioning plate 102 is slidably connected to the sliding groove 105 on the adjusting plate 101 via the sliding structure 106, which facilitates the adjustment of the positioning plate 102 to accommodate car door sills of different widths.

[0044] In one embodiment, it is further preferred that the number of grooves 105 and sliding structures 106 are both a pair.

[0045] To facilitate locking the positioning plate 102 after adjustment and to aid in the installation of the hall door sill, this embodiment is an improvement upon the previous embodiment. The difference lies in that the sliding structure 106 includes a locking bolt 107 and a T-shaped slider 108. The T-shaped slider 108 is positioned on one side of the adjusting plate 101, with one end passing through the slide groove 105 and slidably connected to it. The end of the T-shaped slider 108 passing through the slide groove 105 contacts one side of the positioning plate 102. The locking bolt 107 is positioned on the other side of the positioning plate 102, with one end passing through both the positioning plate 102 and the T-shaped slider 108. The locking bolt 107 is rotatably connected to the positioning plate 102 and threadedly connected to the T-shaped slider 108, used to fix the positioning plate 102 onto the adjusting plate 101.

[0046] When it is necessary to move the positioning plate 102, simply loosen the locking bolt 107 to move the positioning plate 102; once the positioning plate 102 is in place, simply tighten the locking bolt 107 to fix the positioning plate 102.

[0047] To further facilitate the installation of the hall door sill, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a limiting plate 109 is provided on one side of the positioning plate 102, and the limiting plate 109 is fixedly connected to the positioning plate 102.

[0048] The limiting plate 109 is designed to fit against the side of the hall door sill closest to the car door sill, thus facilitating the installation of the hall door sill.

[0049] Since the hinge may cause the adjusting plate 101 to be out of horizontal position when it is flipped, this embodiment is an improvement on the above embodiment in order to make the adjusting plate 101 horizontal. The difference from the above embodiment is that the adjusting plate 101 is provided with a fine adjustment bolt 110. The fine adjustment bolt 110 is located between the slide groove 105 and the connecting structure 104. One end of the fine adjustment bolt 110 passes through the adjusting plate 101 and is threadedly connected to the adjusting plate 101.

[0050] When the adjusting plate 101 is flipped outside the car, observe the angle of the adjusting plate 101, and use the fine-tuning bolt 110 to make the adjusting plate 101 horizontal, thereby improving the installation accuracy of the hall door sill.

[0051] To facilitate the installation of the positioning block 103, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the positioning block 103 is connected to the mounting base plate 100 by a pair of fixing bolts 111. The pair of fixing bolts 111 pass through the mounting base plate 100 and are rotatably connected to the mounting base plate 100. The ends of the pair of fixing bolts 111 are threaded to both ends of the positioning block 103.

[0052] The positioning block 103 is connected to the mounting base plate 100 by a pair of fixing bolts 111, which facilitates the installation and replacement of the positioning block 103.

[0053] As a further preferred option, the positioning block 103 may be made of tool steel, which is a material used in the prior art.

[0054] In order to make it easier to observe whether the adjustment plate 101 is in a horizontal state, a pair of protruding plates 112 are provided on one side of the mounting base plate 100. There is a groove 113 between the pair of protruding plates 112. The adjustment plate 101 can be rotated into the groove 113 and is in clearance fit with the groove 113.

[0055] When in use, you can determine whether the adjusting plate 101 is in a horizontal state by observing whether the adjusting plate 101 is perpendicular to the convex plate 112.

[0056] like Figures 4 to 7 As shown, in order to facilitate the use of this utility model and to facilitate the adjustment of the distance between the pair of positioning components 10, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a connecting component 20 is provided between the pair of positioning components 10. The connecting component 20 includes a telescopic rod 200, a pair of connecting plates 201 and a pair of connecting blocks 202. One side of the pair of connecting plates 201 is fixedly connected to one side of the mounting base plate 100 in the pair of positioning components 10. The pair of connecting blocks 202 are respectively provided on both sides of the telescopic rod 200 and are detachably connected to the telescopic rod 200. The pair of connecting plates 201 are provided with connecting slots 203. The pair of connecting blocks 202 are provided with connecting inserts 204 that cooperate with the connecting slots 203. The connecting inserts 204 can be inserted into the connecting slots 203 and are fixed to the connecting slots 203 by friction.

[0057] The telescopic rod 200 allows for easy adjustment of the distance between the pair of positioning components 10. Simultaneously, the connecting plate 201 and connecting block 202 facilitate quick assembly of this invention and make it convenient to use.

[0058] The telescopic rod 200 can be any existing telescopic rod 200 capable of achieving the functions of this utility model. Alternatively, the following telescopic rod 200 structures can also be used:

[0059] The telescopic rod 200 includes a fixed sleeve 205 and an extension rod 206. The fixed sleeve 205 is provided with an installation groove 207 that cooperates with the extension rod 206. The installation groove 207 passes through both sides of the fixed sleeve 205. One end of the fixed sleeve 205 is provided with a pair of L-shaped connecting blocks 208. The pair of L-shaped connecting blocks 208 are respectively fixedly provided on both sides of the end of the fixed sleeve 205. The pair of L-shaped connecting blocks 208 are respectively detachably connected to one of the connecting blocks 202 by bolts. The fixed sleeve 205 is provided with limiting grooves 209 that communicate with the installation groove 207 on both sides. The limiting grooves 209 pass through the side of the fixed sleeve 205 where the L-shaped connecting blocks 208 are located.

[0060] One end of the extension rod 206 is inserted into the mounting groove 207 and is slidably connected to the mounting groove 207. The end of the extension rod 206 located in the mounting groove 207 is provided with a limiting block 210 that cooperates with the upper limit groove 209 of the fixed sleeve 205. The limiting block 210 is located in the limiting groove 209 and is slidably connected to the limiting groove 209. The other end of the extension rod 206 is provided with a pair of L-shaped connecting seats 211. The pair of L-shaped connecting seats 211 are respectively located on both sides of the end of the extension rod 206 and are detachably connected to the extension rod 206 by bolts. One end of the pair of L-shaped connecting seats 211 is detachably connected to another connecting block 202 by bolts.

[0061] When in use, the telescopic rod 200 is detachable as a whole. During assembly, only the corresponding bolts need to be installed to connect the telescopic rod 200 and the connecting block 202, which facilitates the overall assembly and disassembly of this utility model. At the same time, the detachable connection method makes it easy to carry.

[0062] Working principle of this utility model:

[0063] In use, the mounting base plate 100 of the pair of positioning components 10 is placed on the car door sill, and the positioning block 103 on the mounting base plate 100 is placed in the groove of the car door sill. Then, the adjusting plate 101 is flipped over so that it extends outside the elevator car. The horizontal position of the adjusting plate 101 is then adjusted by the fine-tuning bolt 110 to make it horizontal. The position of the positioning plate 102 is then adjusted so that one side of the positioning plate 102 is aligned with one side of the car door sill, and the other side of the positioning plate 102 corresponds to the side of the hall door sill near the car door sill. When it is necessary to continue installing the hall door sill of the next floor, the adjusting plate 101 is flipped over so that it is inside the car, and the installation can proceed to the next floor.
