Description

Technical Field

[0001] The invention relates to the technical field of installation of standard sections of elevators, in particular to an assembly tool for connecting standard sections of construction elevators. Background Art

[0002] Construction hoists are essential vertical transportation equipment in the construction industry, and their structural stability is directly related to construction safety and efficiency. Standard sections, the main support units of the hoists, are typically assembled section by section using flange-bolted connections. However, existing standard section assembly processes still present the following challenges:

[0003] 1. Reliance on manual experience and insufficient precision: Traditional methods rely on visual inspection or simple positioning tools to align flange holes. These methods are easily affected by lighting, viewing angle, and operator skill, resulting in significant misalignment. Especially when working at height or in complex environments, accumulated errors can cause the structure to tilt, posing a safety hazard.

[0004] 2. Inefficient adjustment: If the flange holes of the upper and lower standard sections are not aligned, repeated hoisting and adjustment are required, which is time-consuming and labor-intensive. For large lifts, a single adjustment may take up to tens of minutes, seriously affecting the construction progress.

[0005] 3. Lack of real-time feedback mechanism: The existing technology lacks an automated alignment detection device, and operators need to frequently pause operations to manually verify the alignment status. The process is cumbersome and it is difficult to ensure consistency.

[0006] While existing technologies have attempted to address these issues with optically assisted alignment, most systems are complex and costly, or rely on external power supplies and precision instruments, making them difficult to adapt to the harsh environments of construction sites. Furthermore, some solutions fail to adequately consider the stability and rapid positioning requirements of the clamping device, making positioning failures prone to vibration or misoperation.

[0007] Therefore, there is an urgent need to develop an assembly tool with a simple structure, easy operation and real-time feedback function to improve the accuracy and efficiency of standard section connections, while reducing dependence on manual experience and ensuring construction safety. Summary of the Invention

[0008] The purpose of the present invention is to provide an assembly tool for connecting standard sections of a construction elevator in response to the above-mentioned problems. Through a simple structure and the use of laser alignment, the accuracy, efficiency and safety of the standard section connection are significantly improved.

[0009] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows:

[0010] According to one aspect of the present invention, there is provided an assembly tool for connecting standard sections of a construction hoist, comprising a first positioning device and a second positioning device;

[0013] It also includes an alignment prompt device, which is connected to the laser emitting component and the laser receiving component respectively, and is used to receive information on the number of laser beams emitted by the laser emitting component and the number of laser beams received by the laser receiving component. When the number of laser beams received by the laser receiving component is consistent with the number of laser beams emitted by the laser emitting component, the alignment prompt device generates alignment information and provides a prompt.

[0016] When an external force acts on the second clamping member to move the second clamping member away from the first clamping member, the first elastic member is deformed. The deformation of the first elastic member forms a clamping area with clamping force between the first clamping member and the second clamping member.

[0017] Preferably, the laser emission assembly includes a laser emission controller and at least three laser emitters, the laser emitters are electrically connected to the laser controller, each of the laser emitters is fixedly arranged on the upper end face of the second clamping member, and at least one of the laser emitters is not collinear with the remaining laser emitters.

[0018] Preferably, it also includes a first auxiliary protrusion adapted to the lower standard section flange hole, the first auxiliary protrusion is fixedly provided on the upper end face of the first clamping member and the lower end face of the second clamping member, and the two first auxiliary protrusions are arranged opposite each other.

[0019] Preferably, the first auxiliary protrusion is in the shape of a cone.

[0021] The third clamping member is connected to the second elastic member, the second connecting rod is connected to the second elastic member, the fourth clamping member is fixedly connected to the second connecting rod, and the third clamping member and the fourth clamping member are arranged opposite to each other;

[0022] When an external force acts on the fourth clamping member to move the fourth clamping member away from the third clamping member, the second elastic member is deformed. The deformation of the second elastic member forms a clamping area with clamping force between the third clamping member and the fourth clamping member.

[0023] Preferably, the laser receiving assembly includes a laser receiving controller and at least three laser receivers, the laser receiving controller is connected to the laser receiver, the laser receiver is evenly fixed on the lower end face of the fourth clamping member, and the laser receiver is arranged in a one-to-one correspondence with the laser transmitter.

[0026] Preferably, the prompt component includes a signal light and a buzzer, and the signal light and the buzzer are electrically connected to the analysis and control chip.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. The laser emitting and receiving components of this invention work in tandem, emitting and receiving multiple laser beams to monitor the alignment of the flange holes of the upper and lower master sections in real time. When all laser beams are received and the number is consistent, the alignment prompt device automatically triggers, completely eliminating manual visual errors and ensuring millimeter-level hole alignment accuracy. Furthermore, repeated hoisting and adjustment are unnecessary during operation; only the upper master section needs to be moved until the alignment prompt device is triggered, significantly reducing single adjustment time and significantly improving construction efficiency.

[0029] 2. The real-time feedback mechanism of the present invention enables operators to confirm the alignment status without interrupting the operation, reducing the frequency of human intervention and lowering labor intensity.

This solves the core issues of low precision, poor efficiency, and reliance on experience in traditional assembly processes, providing reliable guarantees for the safe and efficient assembly of construction elevators.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below with reference to the accompanying drawings and by way of preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help the reader gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be practiced even without these specific details.

[0033] See also Figures 1 to 5 The present invention provides an assembly tool for connecting standard sections of a construction hoist, and the technical solution is as follows:

[0034] An assembly tool for connecting the standard sections of a construction elevator includes a first positioning device 1 and a second positioning device 2. The first positioning device 1 includes a first clamping assembly 3 that can be clamped on the flange hole of the lower standard section and a laser emitting assembly fixedly mounted on the first clamping assembly 3. The first clamping assembly 3 includes a first clamping member, a first connecting rod 32, a first elastic member, and a second clamping member. The first clamping member is connected to the first elastic member, the first connecting rod 32 is connected to the first elastic member, and the second clamping member is connected to the first connecting rod 32. The first clamping member and the second clamping member are arranged opposite to each other. Specifically, the first clamping member is a first L-shaped fixing seat 31, and a first movable hole 4 is provided on the upper end face of the vertical portion of the first L-shaped fixing seat 31. In this embodiment, two first movable holes 4 are provided, and the two first movable holes 4 are arranged at intervals. The first movable hole 4 extends along the vertical portion of the first L-shaped fixing seat 31. A first annular ridge 5 is fixedly provided at the upper end port of the first movable hole 4. A first fixing hole 6 is defined in the middle of the first annular flange 5. One end of the first connecting rod 32 extends through the first fixing hole 6 into the first movable hole 4. The diameter of the first fixing hole 6 of the first annular flange 5 is slightly larger than that of the first connecting rod 32, allowing the first connecting rod 32 to move relative to the first fixing hole 6. A first elastic member is positioned within the first movable hole 4. The first elastic member is a first spring 33, which is sleeved over the end of the first connecting rod 32 positioned within the first movable hole 4. One end of the first spring 33 is fixedly connected to the inner sidewall of the annular flange, and the other end of the first spring 33 is connected to the end of the first connecting rod 32 positioned within the first movable hole 4 via a first pressing plate 17. The first pressing plate 17 is fixedly mounted on the end of the first connecting rod 32, and the first spring 33 is fixedly connected to the first pressing plate 17. The end of the first connecting rod 32 away from the first L-shaped fixing seat 31 is connected to a second clamping member, which is a first plate-shaped fixing seat 34. The lower side of one end of the first plate-shaped fixing seat 34 is fixedly connected to the first connecting rod 32. The first plate-shaped fixing seat 34 is arranged opposite to the horizontal portion of the first L-shaped fixing seat 31. After the staff fixes the first L-shaped fixing seat 31, they pull the first plate-shaped fixing seat 34 (when an external force acts on the first plate-shaped fixing seat 34) to move the first plate-shaped fixing seat 34 away from the first L-shaped fixing seat 31. The end of the first connecting rod 32 placed in the movable hole moves outward from the movable hole, and the pressing plate moves with the first connecting rod 32. The spring is compressed. When the spring is compressed, the pressing plate is pushed by the spring, so that a clamping area with clamping force is formed between the first plate-shaped fixing seat 34 and the horizontal portion of the first L-shaped fixing seat 31. The clamping area with clamping force enables the first clamping assembly 3 to be clamped on the flange hole of the lower standard section.

[0035] A laser emitting assembly is provided on the upper end face of the first plate-shaped fixing seat 34. The laser emitting assembly includes a laser emitting controller and at least three laser emitters 8. In the present embodiment, three laser emitters 8 are provided. The laser emitter 8 is electrically connected to the laser emitting controller. The laser emitting controller includes a laser emitting control chip. Each laser emitter 8 is fixedly provided on the upper end face of the second clamping member, and one of the laser emitters 8 is not collinear with the other laser emitters 8. In the present embodiment, the three laser emitters 8 are evenly spaced at circumferential intervals, and the diameter of the circle formed by the three laser emitters 8 is consistent with the diameter of the lower standard section flange hole. The laser emitter 8 is used to emit a laser beam, and the three laser emitters 8 emit a total of three groups of laser beams.

[0036] The second clamping assembly 7 includes a third clamping member, a second connecting rod 72, a second elastic member, and a fourth clamping member. The third clamping member is connected to the second elastic member, the second connecting rod 72 is connected to the second elastic member, and the fourth clamping member is connected to the second connecting rod 72. The third clamping member and the fourth clamping member are arranged opposite each other. Specifically, the third clamping member is a second L-shaped fixing seat 71. The upper end surface of the vertical portion of the second L-shaped fixing seat 71 is provided with a second movable hole 10. In this embodiment, two second movable holes 10 are provided, spaced apart. The second movable holes 10 extend along the vertical portion of the second L-shaped fixing seat 71. A second annular flange 11 is fixedly mounted at the upper end of the second movable hole 10. A second fixing hole 12 is defined in the middle of the second annular flange 11. One end of the second connecting rod 72 extends through the second fixing hole 12 and into the movable hole. The diameter of the second fixing hole 12 of the second annular flange 11 is slightly larger than that of the second connecting rod 72, allowing the second connecting rod 72 to move relative to the fixing hole. The second elastic member is placed in the second movable hole 10. The second elastic member is a second spring 73. One end of the second spring 73 is fixedly connected to the inner wall of the annular ridge. The other end of the second spring 73 is connected to the end of the second connecting rod 72 placed in the second movable hole 10 through the second pressing plate 18. The second pressing plate 18 is fixedly set at the end of the second connecting rod 72. The second spring 73 is fixedly connected to the second pressing plate 18. The end of the second connecting rod 72 away from the second L-shaped fixing seat 71 is connected to the fourth clamping member. The fourth clamping member is a second plate-shaped fixing seat 74. The lower side of one end of the second plate-shaped fixing seat 74 is fixedly connected to the second connecting rod 72. The second plate-shaped fixing seat 74 is arranged opposite to the horizontal part of the second L-shaped fixing seat 71. The working principle of the second clamping assembly 7 is the same as that of the first clamping assembly 3, and will not be described in detail here. The second clamping assembly 7 can be clamped on the upper standard section flange hole.

[0037] A laser receiving assembly is provided on the lower end face of the second plate-shaped fixing seat 74. The laser receiving assembly includes a laser receiving controller and at least three laser receivers 9. In this embodiment, three laser receivers 9 are provided. The laser receiver 9 is electrically connected to the laser receiving controller. The laser receiving controller includes a laser receiving control chip. Each laser receiver 9 is fixedly provided on the lower end face of the second plate-shaped fixing seat 74, and one of the laser receivers 9 is not collinear with the other laser receivers 9. The laser receivers 9 are provided in a one-to-one correspondence with the laser emitter 8. The diameter of the circle formed by the three laser receivers 9 is consistent with the diameter of the upper standard section flange hole. The laser receiver 9 is used to receive the laser beam emitted by the laser emitter 8.

[0038] The alignment prompt device is connected to the laser emission controller and the laser reception controller, respectively, and is configured to receive information on the number of laser beams emitted and received. When the number of laser beams received matches the number of laser beams emitted, the alignment prompt device generates alignment information and issues a prompt. Specifically, the alignment prompt device comprises a signal receiver, an analysis and control chip, and a prompt component. The signal receiver is connected to the laser emission controller and the laser reception controller, respectively, and is configured to receive information on the number of laser beams emitted by the laser emitter 8 and received by the laser receiver 9. The signal receiver is electrically connected to the analysis and control chip and transmits the information on the number of laser beams emitted and received to the analysis and control chip. The prompt component comprises a signal light 13 and a buzzer 14, each electrically connected to the analysis and control chip. The analysis and control chip compares the information on the number of laser beams emitted and received. If the information on the number of laser beams emitted matches the information on the number of laser beams received, it indicates that the flange holes of the upper and lower standard sections are aligned. The analysis and control chip then controls the signal light 13 to flash or the buzzer 14 to sound, alerting the operator.

[0039] To facilitate the operator's ability to clamp the first clamping assembly 3 onto the flange hole of the lower standard section, this embodiment also includes a first auxiliary protrusion 15 that is compatible with the flange hole of the lower standard section. A first auxiliary protrusion 15 is fixedly mounted on the upper end surface of the horizontal portion of the first L-shaped fixing seat 31 and the lower end surface of the first plate-shaped fixing seat 34. The two first auxiliary protrusions 15 are positioned opposite each other, with the extended axis of the first auxiliary protrusion 15 passing through the center of the circle defined by the three emitters. The first auxiliary protrusion 15 can be snapped into the flange hole of the lower standard section to assist the first clamping assembly 3 in quickly locating the flange hole, allowing the first clamping member to be quickly clamped into the flange hole of the lower standard section.

[0040] Furthermore, a second auxiliary protrusion 16 is included that mates with the flange hole of the upper standard section. A second auxiliary protrusion 16 is fixedly mounted on the lower end surface of the horizontal portion of the second L-shaped fixing seat 71 and the upper end surface of the second plate-shaped fixing seat 74. The two second auxiliary protrusions 16 are positioned opposite each other, with the extended axis of each second auxiliary protrusion 16 passing through the center of the circle defined by the three receivers. The second auxiliary protrusion 16 snaps into the flange hole of the lower standard section, assisting the second clamping assembly 7 in quickly locating the flange hole and enabling the second clamping member to be quickly clamped into the flange hole of the upper standard section.

[0041] Furthermore, the first auxiliary protrusion 15 and the second auxiliary protrusion 16 are conical, and their diameters gradually decrease from the bottom to the top. The conical first auxiliary protrusion 15 and the second auxiliary protrusion 16 can adapt to more standard segment flange holes of different diameters. When the first auxiliary protrusion 15 and the second auxiliary protrusion 16 are inserted into the flange hole, they can better fit with the flange hole, thereby preventing the first clamping component 3 or the second clamping component 7 from loosening. This avoids inaccurate positioning due to loosening and misalignment.

[0042] When in use, the staff first finds the flange hole that needs to be aligned on the lower standard section, and at the same time pulls the first L-shaped fixing seat 31 and the first plate-shaped fixing seat 34 in opposite directions, and inserts the two first auxiliary protrusions 15 into the upper and lower flange holes of the lower standard section respectively, so that the first clamping component 3 is clamped on the flange hole of the lower standard section. Similarly, when the upper standard section has been hoisted above the lower standard section, the staff clamps the second clamping component 7 on the flange hole of the upper standard section, and finally slowly moves the upper standard section until the signal light 13 flashes or the buzzer 14 sounds, indicating that the flange holes of the upper and lower standard sections have been aligned. The upper standard section can then be lowered vertically, and the flange holes of the upper and lower standard sections are connected with bolts to complete the docking work of the upper and lower standard sections.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
