Description

Technical Field

[0001] The utility model relates to the technical field of elevator inclined lower beam assembly, and particularly relates to a positioning tooling for elevator lower beam assembly. Background Technique

[0002] The elevator lower beam is an important part of the elevator drive system. Its main function is to connect the traction wheel, motor and car of the elevator to jointly complete the up and down movement of the elevator. The elevator lower beam is assembled by multiple parts such as two car bottom wheels, two cross beams and a connecting frame.

[0003] At present, during the manufacturing and assembly process of the elevator lower beam, it is necessary to erect two car bottom wheels, and then align the mounting holes at both ends of a cross beam with the central shaft sleeves of the two car bottom wheels and insert them for installation. The two ends of the other cross beam are respectively sleeved on the central shafts on the other side of the car bottom wheels. During this operation process, it is difficult for manual labor to accurately place the two car bottom wheels on the same horizontal plane. Therefore, during the installation process of the cross beam, it is necessary for manual labor to move the positions of the two car bottom wheels multiple times to ensure that the two car bottom wheels are on the same horizontal plane, and the car bottom wheels are prone to rotation or deviation due to human touch. Therefore, during the cross beam installation process, it is also necessary for manual labor to support the car bottom wheels.

[0004] Therefore, a positioning tooling for elevator lower beam assembly is needed to facilitate the precise assembly of the elevator lower beam, car bottom wheels and other parts. Through the precise positioning of the car bottom wheels, the problem that the car bottom wheels deviate from the central shaft and it is difficult to align the holes during the cross beam installation process is prevented, thereby improving the assembly efficiency. Content of the Utility Model

[0005] To solve the above technical problems, a positioning tooling for elevator lower beam assembly is provided, which solves the problems in the prior art that it is difficult for manual labor to accurately place the two car bottom wheels on the same horizontal plane, and the car bottom wheels are prone to rotation or deviation due to human touch. Therefore, during the cross beam installation process, it is also necessary for manual labor to support the car bottom wheels.

[0006] To achieve the above purposes, the technical solution adopted by the utility model is: a positioning tooling for elevator lower beam assembly, characterized in that: it includes two symmetrically arranged support vertical plates and a support cross plate horizontally fixed between the middle parts of the two support vertical plates. On both sides above the support cross plate, there are support members arranged. Through holes are respectively opened on both sides of the top surface of the support cross plate, and a positioning mechanism is arranged in the through holes;

[0007] The support member includes two support blocks, and the two support blocks are respectively detachably connected to the two support vertical plates through bolts;

[0008] The positioning mechanism includes two adjusting blocks symmetrically and slidably arranged in the rectangular hole in the shape of a right trapezoid. The hypotenuses of the two adjusting blocks correspond to each other, and an adjusting component for adjusting the distance between the two adjusting blocks is arranged below the supporting cross plate.

[0009] Preferably, the adjusting component includes a bottom plate horizontally fixed between the two supporting vertical plates. A rectangular sliding groove is formed on the top surface of the bottom plate. A double-sided screw rod is rotatably connected between the inner walls on both sides of the rectangular sliding groove. Limiting sliders are threadedly connected to both sides of the double-sided screw rod body, and the two limiting sliders are respectively fixedly connected to the two adjusting blocks in one-to-one correspondence.

[0010] Preferably, a rotating rod is arranged between the two bottom plates. The two ends of the rotating rod respectively penetrate into the rectangular sliding grooves of the two bottom plates in a rotating manner and are fixedly connected to one ends of the two double-sided screw rods in corresponding positions.

[0011] Preferably, a rotating handle is arranged at one end of one of the bottom plates away from the rotating rod. The rotating handle penetrates into the rectangular sliding groove of the bottom plate in a rotating manner and is fixed to one end of the double-sided screw rod.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] (1) Through the cooperative setting of the supporting member and the positioning mechanism, the two car bottom wheels are respectively placed on two groups of adjusting blocks. The positioning of the car bottom wheels is realized through the setting of the adjusting blocks, preventing the car bottom wheels from rotating due to human touch during the process of assembling the cross beam. Through the setting of the supporting members on both sides, it is ensured that the two car bottom wheels are in the same horizontal position and the front and rear clamping of the car bottom wheels is realized, preventing the car bottom wheels from shifting during the installation of the cross beam.

[0014] (2) Through the detachable connection between the supporting block and the supporting vertical plate, when it is necessary to assemble the cross beam for car bottom wheels with a thinner assembly thickness specification, the bolts on the supporting block can be disassembled to replace the supporting blocks with different thickness specifications, thereby realizing the installation of the cross beam for car bottom wheels with various thickness specifications.

[0015] (3) Through the setting of the adjusting component, when assembling the cross beam for car bottom wheels with a large diameter specification, the car bottom wheels with a large diameter specification can be placed between the inclined surfaces of the two adjusting blocks. The double-sided screw rod can be rotated in the reverse direction, causing the two adjusting blocks to move away from each other. During this process, the car bottom wheels descend along the inclined surfaces of the adjusting blocks due to gravity, and then the central axes on both sides of the car bottom wheels are lowered to a position suitable for sleeving the cross beam installation holes, so that the tooling can meet the requirements of installing cross beams for car bottom wheels with various diameter specifications.

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figure 1 , Figure 2 and Figure 3 as shown, a positioning tooling for assembling the lower beam of an elevator includes two symmetrically arranged support vertical plates 1 and a support horizontal plate 2 horizontally fixed between the middle parts of the two support vertical plates 1. Support members are arranged on both sides above the support horizontal plate 2, and rectangular holes are respectively formed through both sides of the top surface of the support horizontal plate 2. A positioning mechanism is arranged in the rectangular holes;

[0023] The support members include two support blocks 3, and the two support blocks 3 are respectively detachably connected to the two support vertical plates 1 through bolts;

[0024] The positioning mechanism includes two adjusting blocks 5 symmetrically arranged in a right trapezoid shape and sliding in the rectangular holes, and the hypotenuses of the two adjusting blocks 5 correspond to each other;

[0025] Through the cooperative setting of the supporting member and the positioning mechanism, when assembling the elevator lower beam, the two car bottom wheels can be respectively placed on two groups of adjusting blocks 5. The positioning of the car bottom wheels is achieved through the setting of the adjusting blocks 5, preventing the car bottom wheels from rotating due to human touch during the process of assembling the cross beam, and then affecting the distance between the two car bottom wheels, resulting in the installation holes on both sides of the cross beam being unable to align with the central axis of the car bottom wheels. Through the setting of the supporting members on both sides, it is ensured that the two car bottom wheels are in the same horizontal position and the front and rear clamping of the car bottom wheels is realized, preventing the car bottom wheels from shifting during the installation of the cross beam, resulting in the installation holes of the cross beam being unable to align with the central axis of the car bottom wheels. Subsequently, the cross beam is placed above the supporting block 3, and after the installation holes of the cross beam are aligned with the central axis of the car bottom wheels and sleeved, the installation is carried out. In this way, the problem that the car bottom wheels deviate from the central axis and it is difficult to align the holes during the installation of the cross beam can be solved, thereby improving the assembly efficiency. Through the detachable connection between the supporting block 3 and the supporting vertical plate 1, when it is necessary to assemble the cross beam for the car bottom wheels with a thinner assembly thickness specification, the bolts on the supporting block 3 can be removed to replace the supporting blocks 3 with different thickness specifications, and then the installation of the cross beam for the car bottom wheels with various thickness specifications can be realized.

[0026] However, it is found after using for a period of time that this tooling can only be applied to the installation of car bottom wheels with a fixed diameter specification and cannot meet the assembly of products with various diameter specifications.

[0027] In view of this, referring to Figures 1 to 3 As shown, it is worth noting that an adjusting component for adjusting the distance between the two adjusting blocks 5 is provided below the supporting cross plate 2;

[0028] The adjusting component includes a bottom plate 4 horizontally fixed between the two supporting vertical plates 1. A rectangular sliding groove is formed on the top surface of the bottom plate 4. A double-sided screw rod 6 is rotatably connected between the inner walls on both sides of the rectangular sliding groove. Limited sliders 9 are threadedly connected to both sides of the rod body of the double-sided screw rod 6. The two limited sliders 9 are respectively fixedly connected to the two adjusting blocks 5 in a one-to-one correspondence;

[0029] By adjusting the settings of the components, when assembling the crossbeam for a car bottom wheel with a small diameter specification, the double-sided screw 6 can be rotated. Due to the rotation of the double-sided screw 6, the two limiting sliders 9 move relative to each other along the double-sided screw 6 because the limiting sliders 9 are restricted by the inner wall of the rectangular chute. The relative movement of the two limiting sliders 9 drives the two adjusting blocks 5 to move synchronously. When the two adjusting blocks 5 are adjusted to the appropriate positions, the car bottom wheel is placed between the inclined surfaces of the two adjusting blocks 5. Subsequently, the crossbeam is placed above the supporting block 3, and after aligning the crossbeam mounting hole with the central shaft of the car bottom wheel, it is installed. Similarly, when assembling the crossbeam for a car bottom wheel with a large diameter specification, the car bottom wheel with a large diameter specification can be placed between the inclined surfaces of the two adjusting blocks 5, and the double-sided screw 6 can be rotated in the reverse direction, causing the two adjusting blocks 5 to move away from each other. During this process, the car bottom wheel descends along the inclined surface of the adjusting block 5 due to gravity, and then the central shafts on both sides of the car bottom wheel are lowered to the appropriate positions for the crossbeam mounting hole to be sleeved. In this way, the tooling can meet the requirements of assembling crossbeams for car bottom wheels of various diameter specifications.

[0030] After using it for a period of time, it was found that when it was necessary to adjust the position spacing of the two groups of adjusting blocks 5 according to the diameter specification of the car bottom wheel, it was necessary to rotate the two double-sided screws 6 separately. And due to human error, the position spacing of the two groups of adjusting blocks 5 was often unequal. Finally, when the car bottom wheel was placed on the adjusting block 5 for assembling the crossbeam, it was found that the central shafts of the two car bottom wheels were not at the same horizontal height and could not be assembled, so it had to be adjusted again.

[0031] In view of this, to solve the above problems, referring to Figures 1 to 3 As shown, it is worth noting that a rotating rod 7 is arranged between the two bottom plates 4. The two ends of the rotating rod 7 are respectively rotatably inserted into the rectangular chutes of the two bottom plates 4 and are fixedly connected to one end of the two double-sided screws 6 correspondingly. One end of one bottom plate 4 away from the rotating rod 7 is provided with a rotating handle 8, and the rotating handle 8 is rotatably inserted into the rectangular chute of the bottom plate 4 and is fixed to one end of the double-sided screw 6;

[0032] Through the setting of the rotating rod 7 and the rotating handle 8, by rotating the rotating handle 8, one of the double-sided screws 6 is driven to rotate. The rotation of one of the double-sided screws 6 drives the other double-sided screw 6 through the rotating rod 7. In this way, the synchronous rotation of the two double-sided screws 6 can be realized. By using the synchronous rotation of the two double-sided screws 6, the two groups of adjusting blocks 5 can be adjusted synchronously. In this way, the position spacing of the two groups of adjusting blocks 5 can be synchronously adjusted according to the diameter specification of the car bottom wheel, so that the two car bottom wheels are at the same horizontal height, reducing the operation steps in the adjustment process.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
