Description

Technical Field

[0001] The utility model belongs to the technical field of elevator main engine installation, and particularly relates to an auxiliary structure for elevator installation. Background Art

[0002] A lift elevator mainly includes a car, a traction system, a weight balance system, and an electric drive system. The traction motor, that is, the elevator main engine, is the most important component in the electric drive system. In order to ensure the accuracy and stability of the car during movement, the elevator main engine and its working end need to maintain a certain verticality and levelness. Therefore, the bottom of the elevator main engine needs to be fixedly installed through a shock absorber seat with adjustable levelness. The shock absorber seat includes a base fixedly installed on the ground and an adjustment seat arranged on the base. An adjustment mechanism for adjusting the levelness is installed between the adjustment seat and the base. The adjustment seat is driven by the adjustment mechanism to adjust the levelness to ensure the operation of the elevator main engine. Chinese Patent No. CN218403237U discloses an auxiliary structure for installing an elevator shock absorber base, which includes a base and an adjustment seat arranged above the base. An adjustment mechanism for adjusting the levelness of the adjustment seat is installed between the adjustment seat and the base; the top end of the outer side surface of the base bends inward to below the adjustment seat and is parallel to the top surface of the adjustment seat. The top surface of the adjustment seat is provided with a support screw hole and an upper positioning screw hole leading to the top surface of the base. The top surface of the base is also provided with a lower positioning screw hole coaxially arranged with the upper positioning screw hole. There is also a positioning bolt that is screwed into both the upper positioning screw hole and the lower positioning screw hole, and a support bolt that is screwed into the support screw hole and the end of which abuts against the top surface of the base.

[0003] There are still some deficiencies in the above-mentioned auxiliary structure for installing an elevator shock absorber base in the actual use and operation process. Although the cooperation of the positioning bolt and the support bolt can limit the adjustment seat on the base to prevent the adjustment seat from being unstable during the installation of the elevator main engine, during actual installation, we found that a large number of screws and tools are required on-site to horizontally limit and support the adjustment seat. And after the elevator main engine is installed, the positioning bolt and the support bolt need to be disassembled, which is very time-consuming and affects the on-site installation efficiency. Moreover, when the elevator main engine is maintained or the adjustment mechanism between the adjustment seat and the base is maintained later, the positioning bolt and the support bolt need to be disassembled and assembled again, which is very troublesome. Summary of the Utility Model

[0004] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide an auxiliary structure for elevator installation to solve the problems mentioned in the above background art.

[0008] As a preferred technical solution, a threaded hole is opened on the outer side of the base. One end of the threaded hole communicates with the rectangular hole. The threaded end of the hand-tightening bolt is threadedly extended into the rectangular hole through the threaded hole and is inserted into the limiting groove. Through the threaded hole on the base, it is convenient for the hand-tightening bolt to limit the limiting pin column.

[0009] As a preferred technical solution, a first thread groove is opened on the outer side of one end of the limiting pin column. The limiting pin column is threadedly connected with a first hand lever through the first thread groove. One end of the first hand lever away from the limiting pin column movably penetrates through the first through hole. Through the first thread groove, it is convenient to install the first hand lever on the limiting pin column.

[0010] As a preferred technical solution, a second thread groove is opened on the outer side of the lower end of the positioning top column.

[0011] As a preferred technical solution, a limiting angle block is fixedly installed on the outer side of the positioning top column. The shape of the limiting angle block is L-shaped. The limiting angle block is arranged inside the second through hole. Through the limiting angle block, it is convenient to limit the positioning top column for use.

[0012] As a preferred technical solution, one end of the orifice of the rectangular hole corresponds to one end of the orifice of the side groove. The hole shape specifications of the rectangular hole and the pin hole and the groove shape specifications of the side groove are all the same. Through the rectangular hole, the pin hole and the side groove, it is convenient to stably limit the positioning top column through the limiting pin column.

[0013] In summary, the main beneficial effects of the present utility model are as follows:

[0014] When it is necessary to limit the adjusting seat on the base, only need to push up the positioning ejector rod at the square groove of the base from bottom to top so that it inserts into and abuts against the positioning sleeve at the lower end of the adjusting seat, and then move the limit pin column inside the rectangular hole towards the square groove, so that one end of the limit pin column slides through the pin hole on the positioning ejector column and inserts into the side groove inside the square groove to complete the positioning and support of the adjusting seat. Moreover, no external tools are required during the operation process, which greatly facilitates the on-site installation construction. And when the elevator main engine is installed, directly pull the limit pin column away from the positioning ejector column, and the positioning ejector column can lose the bottom support and directly fall into the square groove under the action of gravity. Therefore, there is no need for a secondary disassembly and assembly link, and this structure can be repeatedly used for the adjusting seat during the disassembly and assembly of the elevator main engine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Refer to Figures 1 to 4, an auxiliary structure for elevator installation described in this embodiment includes a base 1. An adjusting seat 2 is provided at the upper end of the base 1. A positioning sleeve 3 is fixedly installed at the lower end of the adjusting seat 2. A square groove 5 is opened at the upper end of the base 1. A positioning top column 4 is slidably connected inside the square groove 5. The upper end of the positioning top column 4 is inserted inside the positioning sleeve 3. A second through hole 14 is opened inside the square groove 5. A pin hole 15 is opened inside the positioning top column 4. A rectangular hole 7 is opened on the outer side of the base 1. A limiting pin column 8 is slidably connected inside the rectangular hole 7. One end of the rectangular hole 7 communicates with the square groove 5. One end of the limiting pin column 8 extends into the square groove 5 and is inserted into the pin hole 15. A side groove 19 is opened on one side of the square groove 5 facing the rectangular hole 7. One end of the limiting pin column 8 passes through the pin hole 15 and is inserted into the side groove 19. A first through hole 12 is opened inside the rectangular hole 7. When it is necessary to limit the adjusting seat 2 on the base 1, only need to push up the positioning top rod at the square groove 5 of the base 1 from bottom to top so that it is inserted and abuts against the positioning sleeve 3 at the lower end of the adjusting seat 2, and then pull the limiting pin column 8 inside the rectangular hole 7 to move towards the square groove 5, so that one end of the limiting pin column 8 slides through the pin hole 15 on the positioning top column 4 and is inserted into the side groove 19 inside the square groove 5 to complete the positioning and support of the adjusting seat 2. And when the elevator main engine is installed, directly pull the limiting pin column 8 away from the positioning top column 4, and after the positioning top column 4 loses the bottom support, it can directly drop into the square groove 5 under the action of gravity, realizing the separation of the positioning top column 4 and the positioning sleeve 3 on the adjusting seat 2; In this technical solution, the basic usage method of the adjusting seat 2 and the base 1 is the same as the basic function of an auxiliary structure for installing an elevator vibration damping base disclosed in the patent with the publication number CN218403237U, so it will not be elaborated too much as the prior art here.

[0021] Reference Figure 2 , a hand-tightening bolt 6 is threadedly connected to the outer side of the base 1. A limiting groove 9 is opened on the outer side of the limiting pin column 8. The threaded end of the hand-tightening bolt 6 extends into the rectangular hole 7 and is inserted into the limiting groove 9. When the limiting pin column 8 slides through the pin hole 15 of the positioning top column 4 and is inserted into the side groove 19, at this time, the limiting groove 9 on the limiting pin column 8 corresponds to the hand-tightening bolt 6. By using the threaded expansion and contraction of the hand-tightening bolt 6 threadedly connected to the base 1, the hand-tightening bolt 6 can extend and be stuck in the limiting groove 9, which can prevent the limiting pin column 8 from moving in the rectangular hole 7.

[0022] Reference Figure 2 , a threaded hole 10 is opened on the outer side of the base 1. One end of the threaded hole 10 communicates with the rectangular hole 7. The threaded end of the hand-tightening bolt 6 threadedly extends into the rectangular hole 7 through the threaded hole 10 and is inserted into the limiting groove 9. By using the threaded hole 10 on the base 1, it is convenient for the threaded end of the hand-tightening bolt 6 to threadedly expand and contract on the base 1, facilitating the limitation of the limiting pin column 8.

[0023] Reference Figure 2, a first screw groove 11 is provided on the outer side of one end of the limit pin column 8. The limit pin column 8 is threadedly connected with a first hand lever 13 through the first screw groove 11. One end of the first hand lever 13 away from the limit pin column 8 movably penetrates through the first through hole 12. By using the first screw groove 11 at one end of the limit pin column 8, the first hand lever 13 can be conveniently installed. And by using the first hand lever 13 to penetrate through the first through hole 12, the limit pin column 8 can be conveniently pushed and pulled horizontally in the rectangular hole 7.

[0024] Reference Figure 3 , a second screw groove 18 is provided on the outer side of the lower end of the positioning top column 4. The positioning top column 4 is threadedly connected with a second hand lever 16 through the second screw groove 18. One end of the second hand lever 16 away from the positioning top column 4 movably penetrates through the second through hole 14. By using the second screw groove 18 on the positioning top column 4, the second hand lever 16 can be conveniently installed. And after the second hand lever 16 penetrates through the second through hole 14, the second hand lever 16 can be used to conveniently push and pull the positioning top column 4 vertically.

[0025] Reference Figure 3 , a limit angle block 17 is fixedly installed on the outer side of the positioning top column 4. The shape of the limit angle block 17 is L-shaped. The limit angle block 17 is arranged inside the second through hole 14. By using the limit angle block 17 on the positioning top column 4, the upward movement of the positioning top column 4 can be conveniently limited. After the upper end of the positioning top column 4 is inserted into and abuts against the positioning sleeve 3, and the lower end is limited by the limit angle block 17, the pin hole 15 on the positioning top column 4 can be on the same horizontal line as the side groove 19 and the rectangular hole 7, so that the limit pin column 8 can conveniently limit the lower end of the positioning top column 4.

[0026] Reference Figure 2 and Figure 3 and Figure 4 , one end of the orifice of the rectangular hole 7 corresponds to one end of the orifice of the side groove 19. The hole shape specifications of the rectangular hole 7 and the pin hole 15 and the groove shape specifications of the side groove 19 are the same. The rectangular hole 7, the side groove 19 and the pin hole 15 adopt the same specifications, which can facilitate the limit pin column 8 to limit the positioning top column 4.

[0027] Principle and advantages of use: During the use process, when installing the elevator main engine, first, the adjusting seat 2 needs to be limited. When it is necessary to limit the adjusting seat 2 on the base 1, only need to push up the positioning top rod at the square groove 5 of the base 1 from bottom to top so that it is inserted into and abuts against the positioning sleeve 3 at the lower end of the adjusting seat 2. Then, by pulling the limit pin column 8 inside the rectangular hole 7 to move towards the square groove 5, one end of the limit pin column 8 slides through the pin hole 15 on the positioning top column 4 and then inserts into the side groove 19 inside the square groove 5, and the positioning and support of the adjusting seat 2 can be completed. Then, by using the threaded expansion of the hand-tightening bolt 6 threadedly connected to the base 1, the hand-tightening bolt 6 can extend into and be stuck in the limit groove 9, which can prevent the limit pin column 8 from moving in the rectangular hole 7;

[0028] After the elevator main machine is installed, turn the hand-tightening bolt 6 to separate it from the limit pin column 8, and then directly pull the limit pin column 8 away from the positioning top column 4. After the positioning top column 4 loses the bottom support, it can directly enter the square groove 5 under the action of gravity, realizing the separation of the positioning top column 4 from the positioning sleeve 3 on the adjusting seat 2.
