Description

Technical Field

[0001] The present application relates to the technical field of process equipment required for processing paper cups of passenger elevator car structural components in the machinery manufacturing industry, and in particular to a tooling for ensuring the installation accuracy of the wheel beam of a passenger elevator car frame, which is particularly suitable for the finished product connection accuracy of the wheel beam of the TP and TJ series elevator car frames with a single car in a machine room and a single car without a machine room, so as to ensure the connection stability of the wheel beam under load conditions. Background Art

[0002] Elevator is a general term for vertical transportation tools and fixed lifting equipment within buildings. Passenger elevator, also known as passenger elevator, is a special elevator for transporting passengers. It requires complete safety facilities and certain interior decoration. It is the most widely used elevator at present.

[0003] Passenger elevators are composed of traction systems, guide systems, counterweight devices, safety devices, electric traction systems, signal control systems, hall doors, cars, etc. The car is an elevator component that transports passengers and goods. It is the working part of the elevator, the part where passengers (occupants) directly contact with goods, and the part that passengers (occupants) have intuitive cognition. The car consists of a car frame and a car body. The car frame (hanger) is the load-bearing mechanism of the car, which is composed of upper beams, lower beams (bottom beams), columns (side beams) and pull rods (pull rods) and other components. Its function is to fix and suspend the car. At the bottom of the car frame is the wheel beam. As the name suggests, the wheel beam is composed of two relatively independent devices, wheels and beams, to realize the support and movement functional structural parts under the load-bearing condition of the car. In the middle of the bottom wheel beam is an independent crossbeam, and on both sides are rotating wheels and their support seats (wheel seats). The beam and the wheel seat are connected by high-strength fasteners to form a relatively integral functional device.

[0004] The main functions of the beam in the bottom wheel beam include: first, spacing, that is, according to the width of the elevator car frame, the length of the beam determines the consistency and matching of the length of the whole wheel beam with the width of the elevator car frame; second, load-bearing, that is, the beam bears the gravity of the whole wheel beam, especially the reciprocating load during the high-speed vertical operation of the elevator car frame; third, connection, on the one hand, the two longitudinal ends connect two sets of independent wheels, and on the other hand, the middle plane of the beam is connected to the bottom of the elevator car frame, that is, the whole set of wheel beams and the elevator car frame are connected into one. Therefore, the connection accuracy and stability of the wheel seat and the beam are the key processes in the assembly of the wheel beam, and are also important indicators of the overall installation accuracy of the car frame in the elevator shaft of the building. At present, the connection and assembly process of the wheel seat and the beam is to place the beam on the working platform first, use the bottom plane of the beam and the wheel seat as the installation reference plane, align them synchronously, connect 16 high-strength bolts, and then install the traction wheel. This method does not require special or dedicated tooling, as long as it can be assembled on a platform with sufficient length and width, which is in line with the business characteristics of labor-intensive enterprises.

[0005] However, the above installation method still has shortcomings. This operation method needs to rely on a working platform and use the bottom plane of the beam and the wheel seat as the assembly reference. It does not require any positioning tooling and is entirely done by the skills and experience of the operators. It requires high skills and experience of the operators. In addition, this operation method uses a single-side wheel seat to connect with the beam, and then connects the other side wheel seat to the beam. During this period, it involves two directional assemblies of the beam and the wheel seat. In the absence of beam or wheel seat positioning, displacement is likely to occur, affecting the assembly accuracy. In actual installation, there are various length specifications of the wheel beam for the car frame. With the help of a working platform for assembly and fixation, it is necessary to adjust according to different lengths. The existing working platform does not have the conditions for rapid adjustment and assembly, which is not conducive to multi-specification and multi-batch assembly operations. Utility Model Content

[0032] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0033] The embodiment of the present application discloses a tool for ensuring the installation accuracy of a wheel beam of a passenger elevator car frame.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a tooling for ensuring the installation accuracy of the wheel beam of a passenger elevator car frame includes a base 1, on which a slide rail 2 is installed, and a plurality of slide rails 2 are provided. In this embodiment, two slide rails 2 are arranged side by side, and a mounting seat 3 is slidably arranged on the slide rail 2. Two mounting seats 3 are arranged on the slide rail 2, and the two mounting seats 3 are arranged opposite to each other. The mounting seats 3 slide synchronously on the two slide rails 2, and a wheel seat positioning assembly 4 for positioning the wheel seat 20 is arranged on the mounting seat 3. A beam positioning member for positioning the beam 30 is also arranged on the mounting seat 3.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the wheel seat positioning assembly 4 includes a placement seat 41 and a pin shaft 42. A positioning groove 5 is provided on the pin shaft 42. The positioning groove 5 is annular, and two positioning grooves 5 are provided, which are respectively located at both ends of the pin shaft 42. A V-shaped groove 8 is provided above the placement seat 41, and the pin shaft 42 is placed in the V-shaped groove 8. The placement seat 41 is also provided with an end limiter and a vertical limiter for limiting the pin shaft 42. The end limiter is an end stopper 6 detachably connected to the placement seat 41 by bolts. Two end stops 6 are provided, and the two end stops 6 are respectively connected to different ends of the placement seat 41 to prevent the pin shaft 42 from being placed in the V-shaped groove. 8, and then move along the through-point of the V-groove 8, thereby limiting the horizontal movement of the pin shaft 42 after it is placed on the V-groove 8. The vertical limiter is a clamping plate 7 that is detachably connected to the placement seat 41 by bolts. The middle part of the clamping plate 7 is arc-shaped and is arranged in cooperation with the top of the pin shaft 42. When the pin shaft 42 is placed in the V-groove 8, the clamping plate 7 is installed on the placement seat 41. The clamping plate 7 will be pressed onto the pin shaft 42, thereby limiting the vertical movement of the pin shaft 42 after it is placed on the V-groove 8. The placement seat 41, the end stop 6, and the clamping plate 7 work together to limit and lock the pin shaft 42 in the V-groove 8 on the placement seat 41. When in use, when the wheel frame is placed on the placement seat 41, the frame part of the wheel frame is aligned with the positioning groove 5 on the pin shaft 42, and then the wheel frame is moved so that the wheel frame is embedded in the positioning groove 5. At this time, the bottom of the wheel frame is attached to the mounting seat 3, and the wheel frame is also limited by the placement seat 41 and the positioning groove 5 at the same time, thereby realizing the horizontal limitation of the wheel frame.

[0036] like Figure 2 , Figure 4As shown, the beam positioning member is an adjusting bolt 9 threadedly connected to the mounting seat 3, and a plurality of adjusting bolts 9 are provided. In the present embodiment, three adjusting bolts 9 are provided, and the three adjusting bolts 9 are arranged in an equilateral triangle. In order to ensure that the position of the adjusting bolts 9 is fixed after adjustment, a locking nut 10 is threadedly connected to the adjusting bolt 9. When in use, the staff needs to adjust the three adjusting bolts 9 to be at the same height at one end away from the mounting seat 3. After the adjustment is completed, the locking nut 10 is rotated so that the locking nut 10 fits on the mounting seat 3, and the adjusting bolt 9 can be locked. When the beam 30 needs to be positioned, one end of the beam 30 will fit on the adjusting bolt 9 on one mounting seat 3, and the other end of the beam 30 will fit on the adjusting bolt 9 on another mounting seat 3, thereby limiting and supporting the beam 30 and positioning the beam 30.

[0037] The implementation principle of the embodiment of the present application is as follows: when it is put into actual use, the user first installs the wheel seat 20 on the corresponding wheel seat positioning assembly 4, places the seat 41 and the pin shaft 42 to position the wheel seat 20, and makes the two wheel seats 20 relatively arranged. After the two wheel seats 20 are installed, the distance between the two mounting seats 3 is adjusted, and the cross beam 30 is installed from top to bottom. One end of the cross beam 30 is attached to the adjusting bolt 9 on one mounting seat 3, and the other end of the cross beam 30 is attached to the adjusting bolt 9 on the other mounting seat 3. At this time, the reserved hole position on the cross beam 30 is just aligned with the reserved hole position on the wheel seat 20. The staff can easily and quickly connect the locking bolts to complete the connection between the cross beam 30 and the wheel seat 20. After the connection is completed, it is removed and the next set of connection can be carried out. When the sizes of multiple sets of cross beams 30 are the same, the distance between the two mounting seats 3 can be kept unchanged and used repeatedly, which is convenient for quick assembly, ensures assembly accuracy, and improves assembly efficiency.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
