Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator shaft work frame. Background Technology

[0002] Elevator installation requires laying elevator guide rails inside the elevator shaft, which involves drilling holes in the shaft's inner wall. Current elevator installation methods primarily rely on traction ropes to move a work frame up and down within the shaft, allowing for drilling operations at different locations. To ensure smooth lifting and adjustment of the work frame, multiple lifting mechanisms are installed at different positions on the work frame, allowing the traction ropes to pass through them. This results in multiple traction ropes distributed circumferentially around the drilling equipment's working area, which can easily interfere with drilling operations. Furthermore, the multiple traction ropes limit the working area of ​​the drilling equipment, affecting the ease of position adjustment. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Figure 1 A schematic diagram of the elevator shaft working frame in an embodiment of this utility model is shown. Figure 2A cross-sectional view of the elevator shaft work frame in an embodiment of the present invention is shown. The elevator shaft work frame includes: a frame body 1, a guide mechanism 3 disposed on the frame body 1, and two or more lifting mechanisms 2. The frame body 1 is connected to the traction rope inside the elevator shaft based on the lifting mechanism 2. The frame body 1 realizes climbing operation inside the elevator shaft based on the lifting mechanism 2. By adjusting the horizontal height position of the frame body 1 inside the elevator shaft with the lifting mechanism 2 and the traction rope, the processing needs of different positions inside the elevator shaft can be met.

[0031] At least one of the lifting mechanisms 2 and the guiding mechanism 3 cooperate to form a guiding and avoidance path for the traction rope. Based on the guiding mechanism 3, the routing path of the traction rope of the lifting mechanism 2 inside the frame body 1 can be changed, and the cooperation relationship between the traction rope and the frame body 1 can be adjusted.

[0032] The output direction of the traction ropes of two or more lifting mechanisms 2 is concentrated on one side of the bottom of the work frame based on the guide avoidance path. When the traction rope passes through the lifting mechanism 2, it runs along the guide avoidance path and extends from below one end of the frame body 1. The setting position of the traction rope is adjusted based on the guide mechanism 3 to avoid the traction rope from interfering with the construction equipment of the work frame, and to ensure that the bottom of the work frame has sufficient construction space to meet the processing requirements of elevator shaft drilling construction.

[0033] Furthermore, by setting the output direction of the traction ropes of two or more lifting mechanisms 2 on the same side of the elevator shaft working frame, it is possible to avoid the traction ropes interfering with the working movement of the drilling equipment on the working frame.

[0034] Specifically, the bottom of the work frame is provided with an installation area for installing drilling equipment. The drilling equipment is movably connected to the bottom of the work frame based on a guide rail slider, so that the working range of the drilling equipment can cover all directions of the bottom of the work frame. By adjusting the position of the drilling equipment, the drilling equipment can be used to drill holes in different inner walls of the elevator shaft, so as to install and lay elevator guide rails inside the elevator shaft.

[0035] Furthermore, the traction ropes output from the bottom of the work frame can be organized on the same side by the guide mechanism 3, so that the drilling equipment has sufficient room to move when adjusting its own position and avoids the traction ropes interfering with the movement of the drilling equipment.

[0036] Two or more lifting mechanisms 2 are symmetrically distributed inside the frame body 1, so that the frame body 1 can maintain a balanced state based on the lifting mechanisms 2. At the same time, the overall structural arrangement inside the frame can be adjusted so that the overall structural mass distribution of the work frame is uniform, which meets the adjustment requirements of the frame body 1 to move up and down inside the elevator shaft.

[0037] Specifically, Figure 3 A schematic diagram of the guide mechanism 3 of the elevator shaft work frame in this embodiment of the present invention is shown. The guide mechanism 3 is disposed inside the frame body 1. The guide mechanism 3 includes a guide groove 33 and a plurality of pulleys. The plurality of pulleys include at least a first fixed pulley 31 located at the lower end of the lifting mechanism 2 and a second fixed pulley 32 located on one side of the frame body 1. The guide groove 33 is disposed between the first fixed pulley 31 and the second fixed pulley 32. The guide groove 33 adjusts the direction of the traction rope based on the first fixed pulley 31 and the second fixed pulley 32, and meets the requirements of the traction rope's movement.

[0038] Furthermore, the guide groove 33 is configured as a square pipe structure. Based on the guide groove 33, the traction rope passing through the inside of the frame body 1 is sleeved and protected to avoid the collision between the internal structure of the frame body 1 and the traction rope during the relative movement of the work frame and the traction rope, thereby improving the safety of the movement coordination between the frame body 1 and the traction rope.

[0039] Specifically, the first fixed pulley 31 and the second fixed pulley 32 are staggered in the horizontal direction, and / or staggered in the vertical direction. According to the arrangement requirements of the lifting mechanism 2 inside the frame body 1, the positions of the first fixed pulley 31 and the second fixed pulley 32 inside the frame body 1 are adjusted so that the guide avoidance path can meet the arrangement of the internal structure of the frame body 1, avoid the guide mechanism 3 from interfering with the internal structure of the frame body 1, and ensure that the internal structure of the frame body 1 can be reasonably arranged to meet the installation requirements between the various components inside the frame body 1.

[0040] Furthermore, the first fixed pulley 31 and the second fixed pulley 32 can adjust the routing direction of the traction rope within the frame body 1, thereby satisfying the structural fit relationship of the work frame.

[0041] Specifically, the elevator shaft work frame also includes a guide mechanism 4, which is disposed on one side of the work frame. The elevator shaft work frame is connected to the guide rope of the elevator shaft based on the guide mechanism 4. The guide rope is disposed inside the elevator shaft and is set to a vertically taut state. Based on the guide rope, the movement direction of the work frame can be guided, so that the elevator shaft work frame can move up and down in the vertical direction, ensuring the reliability of the movement of the elevator shaft work frame.

[0042] Specifically, the guiding mechanism 4 includes a first limiting wheel group 41 and a second limiting wheel group 42 arranged vertically. The first limiting wheel group 41 is located at the top of the work frame, and the second limiting wheel group 42 is located at the bottom of the work frame. The first limiting wheel group 41 and the second limiting wheel group 42 are arranged on the same vertical line. The guide rope of the elevator shaft enters the work frame through the first limiting wheel group 41, and the guide rope is output outward from the work frame through the second limiting wheel group 42. The guide rope of the elevator shaft is limited and adjusted based on the first limiting wheel group 41 and the second limiting wheel group 42 to meet the assembly requirements between the work frame and the guide rope.

[0043] Furthermore, the first limiting wheel set 41 and the second limiting wheel set 42 are used to adapt to the wiring connection of the guide rope, so that the work frame can move up and down in the elevator shaft along the guide rope.

[0044] Specifically, a guide tube 43 is provided between the first limiting wheel group 41 and the second limiting wheel group 42. The guide tube 43 is sleeved on the outside of the guide rope. That is, when the guide rope passes through the elevator shaft working frame, it can pass through the guide tube 43 and then be output to the outside of the working frame. Based on the guide tube 43, the guide rope passing through the inside of the frame body 1 is sleeved and protected, so as to avoid the collision between the internal structure of the frame body 1 and the guide rope during the relative movement of the working frame and the guide rope, thereby improving the safety of the movement coordination between the frame body 1 and the guide rope.

[0045] Specifically, the first limiting wheel assembly 41 includes a mounting plate 413, a first sub-pulley 411, and a second sub-pulley 412. The first sub-pulley 411 and the second sub-pulley 412 are arranged side by side on the mounting plate 413. The mounting plate 413 includes a first sub-plate and a second sub-plate arranged in parallel. The first sub-pulley 411 and the second sub-pulley 412 are disposed between the first sub-plate and the second sub-plate, so that the first sub-pulley 411 and the second sub-pulley 412 can be installed side by side in the mounting plate 413, thereby forming an assembly gap for accommodating the guide rope between the first sub-pulley 411 and the second sub-pulley 412. Based on the first sub-pulley 411 and the second sub-pulley 412, the first limiting wheel assembly 41 can form a sliding engagement with the guide rope, that is, the frame body 1 can move relative to the guide rope based on the first limiting wheel assembly 41.

[0046] Specifically, the first limiting wheel assembly 41 further includes an adjustment component 414, the second sub-pulley 412 is fixed on the mounting plate 413, and the first sub-pulley 411 is adjustablely mounted on the mounting plate 413 based on the adjustment component 414. The size of the assembly gap between the first sub-pulley 411 and the second sub-pulley 412 can be adjusted by the adjustment component 414 to ensure that the first limiting wheel assembly 41 has good contact friction with the guide rope.

[0047] Specifically, Figure 4 The diagram shows a schematic of the structure of the first limiting wheel assembly 41 of the guide mechanism 4 in an embodiment of the present invention. The adjusting assembly 414 includes: a support shaft 4141, a spring 4142 sleeved on the support shaft 4141, and a nut 4143. The mounting plate 413 is provided with a groove structure. The rotation shaft of the first sub-pulley 411 extends into the groove structure. One end of the support shaft 4141 abuts against the rotation shaft of the first sub-pulley 411, and the spring 4142 is located between the rotation shaft of the first sub-pulley 411 and the inner wall of the groove structure. The other end of the support shaft 4141 extends to the outside of the mounting plate 413, and the nut 4143 is threaded onto the other end of the support shaft 4141. By rotating the nut 4143, the length of the end of the support shaft 4141 assembled in the groove structure is reduced proportionally, thereby compressing the spring 4142 to form a compressed state. This allows the first sub-pulley 411 to cooperate with the second sub-pulley 412 based on the compression force of the spring 4142 to press the guide rope, ensuring the stability of the cooperation between the guide rope and the first limiting wheel group 41.

[0048] Furthermore, the contact friction between the first limiting wheel set 41 and the guide rope is adjusted based on the adjustment component 414, so that the friction between the first limiting wheel set 41 and the guide rope satisfies the relative movement between the frame body 1 and the guide rope.

[0049] Furthermore, the second limiting wheel set 42 has the same structure and technical effects as the first limiting wheel set 41, which will not be described in detail here.

[0050] Specifically, the motion principle of the frame body 1 is as follows: the power provided by the lifting mechanism 2 during operation is greater than the contact friction between the frame body 1 and the traction rope and the contact friction between the frame body 1 and the guide rope, so that the frame body 1 can climb along the traction rope and maintain vertical lifting and lowering motion based on the guide rope.

[0051] When the frame body 1 moves to the preset working position height, the lifting mechanism 2 stops driving and locks the work frame based on the locking device set on the frame body 1, so as to meet the drilling operation inside the elevator shaft on the work frame.

[0052] This utility model embodiment provides an elevator shaft work frame. By setting a guide mechanism 3 inside the frame body 1, a guide avoidance path is formed inside the frame body 1 based on the guide mechanism 3. This allows the traction rope passing through the lifting mechanism 2 to be neatly arranged along the guide avoidance path and output on one side of the bottom of the work frame. This avoids the traction rope being located around the working area of ​​the drilling equipment, thereby avoiding the traction rope causing limiting interference to the drilling equipment. This allows the drilling equipment to have sufficient working space for position adjustment, improving the convenience of adjusting the position of the drilling equipment. At the same time, it avoids the traction rope interfering with the drilling operation of the drilling equipment, ensuring the processing quality of the drilling equipment.

[0053] Furthermore, the above description of an elevator shaft work frame provided by the embodiments of this utility model has been detailed. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
