Description

Technical Field

[0001] This utility model relates to the field of guide shoe technology, and in particular to a roller guide shoe that is easy to install. Background Technology

[0002] Guide shoes are sliding nylon blocks between the elevator guide rails and the car. They secure the car to the guide rails, allowing it to move only up and down. Each elevator car has four sets of guide shoes installed, one on each side of the upper beam and the other below the safety gear seat at the bottom of the car. Four sets of counterweight guide shoes are installed at the bottom and top of the counterweight beam. The guide shoes fixed to the car can move back and forth along fixed guide rails installed on the building shaft walls, preventing the car from tilting or swaying during operation. Elevator guide shoes are divided into rolling guide shoes and sliding guide shoes. Rolling guide shoes, also known as roller guide shoes, use three or six wheels that are engaged with the guide rails. Installing roller guide shoes requires on-site adjustments by operators to ensure the rollers are properly aligned with the guide rails, which is time-consuming, labor-intensive, and requires a high level of installation skill; otherwise, the installation quality may be compromised. Therefore, a more easily installed roller guide shoe is needed. Utility Model Content

Detailed Implementation

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1 to 6 This utility model embodiment provides an easy-to-install roller guide shoe 301, characterized in that it includes:

[0028] The mounting bracket 1 is provided with a first mounting part 101 and two second mounting parts 102, with the two second mounting parts 102 distributed on both sides of the first mounting part 101;

[0029] Guide block 2, which is detachably connected to the mounting bracket 1, is provided with guide groove 201, the position of guide groove 201 corresponding to the position of the first mounting part 101 and the two second mounting parts 102;

[0030] The wheel set 3 includes a roller 301, a connecting arm 302, an elastic shock absorption mechanism 4, and a buffer mechanism 5. The roller 301 is rotatably connected to the connecting arm 302 via a rotating shaft 303. The connecting arm 302 is provided with a rotating part 304, which is rotatably connected to the mounting bracket 1. The elastic shock absorption mechanism 4 passes through the upper part of the connecting arm 302, and one end of the elastic shock absorption mechanism 4 is detachably connected to the mounting bracket 1. The buffer mechanism 5 passes through the middle part of the connecting arm 302, and one end of the buffer mechanism 5 is detachably connected to the mounting bracket 1. The rotating shaft 303 is located between the elastic shock absorption mechanism 4 and the buffer mechanism 5. There are three sets of wheel sets 3, which are respectively located on the first mounting part 101 and two second mounting parts 102.

[0031] This utility model provides an easy-to-install roller guide shoe 301, characterized by comprising: a mounting bracket 1, a guide block 2, and wheel sets 3. Before installation, the guide block 2, matching the size of the guide rail, is selected and installed on the mounting bracket 1. The three wheel sets 3 are respectively installed on the first mounting part 101 and the two second mounting parts 102, so that the positions of the three rollers 301 correspond to the positions of the guide grooves 201. During installation, simply snap the guide grooves 201 onto the guide rail first, and then snap the rollers 301 onto the guide rail to ensure that all three rollers 301 are installed in place. The installation process is simple and convenient. This can effectively improve the installation efficiency during on-site installation. After the roller 301 guide shoe is installed, the guide block 2 is removed to ensure that the elastic damping mechanism 4 can play a damping role. The mounting bracket 1 is used to install on the elevator car. When the elevator is running, the roller 301 abuts against the guide rail. When shaking, the elevator car shakes with the mounting bracket 1. At this time, under the action of the elastic damping mechanism 4 and the connecting arm 302, the roller 301 swings around the rotating part 304 of the connecting arm 302 and always abuts against the elevator guide rail. In this process, the elastic damping mechanism 4 can play a damping role, making the user ride the elevator more comfortable.

[0032] In a further embodiment of this embodiment, the guide groove 201 has a first positioning surface 202, the position of the first positioning surface 202 corresponds to the position of the first mounting part 101, and the guide groove 201 also has two opposing second positioning surfaces 203, the second positioning surfaces 203 are distributed on both sides of the first positioning surface 202, and the positions of the two second positioning surfaces 203 correspond to the positions of the two second mounting parts 102 respectively.

[0033] In this embodiment, the guide groove 201 has a first positioning surface 202 and two second positioning surfaces 203. The position of the first positioning surface 202 corresponds to the position of the roller 301 installed on the first mounting part 101, and the position of the second positioning surface 203 corresponds to the position of the roller 301 installed on the second mounting part 102. The guide block 2 is positioned with the guide rail through the first positioning surface 202 and the second positioning surface 203. The structure is simple and the operation is convenient.

[0034] In a further embodiment of this example, a transition arc surface 204 is provided between the first positioning surface 202 and the second positioning surface 203.

[0035] In this embodiment, there is a transition arc surface 204 between the first positioning surface 202 and the second positioning surface 203, which avoids stress concentration caused by direct connection between the first positioning surface 202 and the second positioning surface 203, and can effectively improve the structural strength of the guide block 2. The transition arc surface 204 does not contact the guide rail and does not require high machining accuracy, thus effectively reducing the machining difficulty and saving production costs.

[0036] In a further embodiment of this invention, a guide slope 205 is provided at the opening of the guide groove 201. The guide slope 205 is inclined toward the inside of the guide groove 201, and the second positioning surface 203 is connected to the guide slope 205.

[0037] In this embodiment, a guide slope 205 is provided at the opening of the guide groove 201. When the guide block 2 is snapped onto the guide rail, the guide slope 205 can play a guiding role, making it easier for the operator to snap the guide block 2 onto the guide rail, thereby further improving the installation efficiency.

[0038] In a further embodiment of this invention, the top of the mounting bracket 1 is provided with a first mounting hole 103, and the guide block 2 is provided with a second mounting hole 206. The first mounting hole 103 and the second mounting hole 206 are coaxially arranged.

[0039] In this embodiment, the top of the mounting bracket 1 is provided with a first mounting hole 103, and the guide block 2 is provided with a second mounting hole 206. The first mounting hole 103 is a threaded hole. The guide block 2 is mounted on the mounting bracket 1 by bolts. During installation, the bolts pass through the second mounting hole 206 and are threadedly connected to the first mounting hole 103. The operation is simple and the installation is convenient. It is easy for the operator to remove the guide block 2 after the roller 301 guide shoe is installed, which further improves the installation efficiency.

[0040] In a further embodiment of this invention, the top of the mounting bracket 1 is provided with a mounting groove 104, the outer side wall of the guide block 2 abuts against the inner side wall of the mounting groove 104, the side of the mounting bracket 1 is provided with a positioning protrusion 207, and the positioning protrusion 207 is provided with the second mounting hole 206.

[0041] In this embodiment, the top of the mounting bracket 1 is provided with a mounting groove 104. When installing the guide block 2, the guide block 2 is inserted into the mounting groove 104, and the lower part of the positioning protrusion 207 abuts against the top of the mounting bracket 1. By setting the mounting groove 104, a positioning effect can be achieved, which makes it easier for the operator to install the guide block 2 onto the mounting bracket 1, thereby further improving the installation efficiency.

[0042] In a further embodiment of this invention, the elastic damping mechanism 4 includes a first screw 401, a first adjusting nut 402, and a damping spring 403. The upper part of the connecting arm 302 is provided with a damping hole 305. The first screw 401 is inserted into the damping hole 305. The first end of the first screw 401 is threadedly connected to the mounting bracket 1. The first adjusting nut 402 is threadedly connected to the second end of the first screw 401. The damping spring 403 is sleeved on the first screw 401 and is disposed between the connecting arm 302 and the first adjusting nut 402.

[0043] In this embodiment, the elastic damping mechanism 4 includes a first screw 401, a first adjusting nut 402, and a damping spring 403. The damping hole 305 is an oblong hole. When the roller 301 swings around the rotating part 304 of the connecting arm 302, the screw is fixed on the mounting bracket 1, and the connecting arm 302 compresses the damping spring 403, thereby limiting the swing of the connecting arm 302 and thus achieving the effect of damping. The first adjusting nut 402 is threadedly connected to the first screw 401. Tightening the first adjusting nut 402 can adjust the relative position of the first adjusting nut 402 on the first screw 401, thereby adjusting the distance from the first adjusting nut 402 to the connecting arm 302, which can adjust the elasticity of the damping spring 403, thus providing a better damping effect for elevator cars of different sizes.

[0044] In a further embodiment of this invention, the elastic damping mechanism 4 further includes a spring seat 404, which is sleeved on the first screw 401. The spring seat 404 is disposed between the damping spring 403 and the first adjusting nut 402. The spring seat 404 includes a positioning ring 405, the interior of which protrudes to one side to form a positioning part 406. The positioning part 406 is inserted into the damping spring 403, and the positioning ring 405 abuts against the end of the damping spring 403.

[0045] In this embodiment, the elastic damping mechanism 4 further includes a spring seat 404. The positioning part 406 of the spring seat 404 is inserted into the damping spring 403, which can prevent the damping spring 403 from deviating from its position during compression, thereby ensuring that the damping spring 403 can play an effective damping role.

[0046] In a further embodiment of this invention, the buffer mechanism 5 includes a second screw 501, a second adjusting nut 502, and a shock-absorbing pad 503. The second screw 501 passes through the connecting arm 302 and is connected to the mounting bracket 1. The first end of the second screw 501 is threadedly connected to the mounting bracket 1. The second adjusting nut 502 is threadedly connected to the second end of the second screw 501. The shock-absorbing pad 503 is sleeved on the second screw 501 and is disposed between the connecting arm 302 and the second adjusting nut 502.

[0047] In this embodiment, the first end of the second screw 501 is threadedly connected to the mounting bracket 1, the second adjusting nut 502 is installed on the second end of the second screw 501, and the shock-absorbing pad 503 is a rubber pad. When the elevator load is large and the swaying amplitude is too large, the shock-absorbing spring 403 may not be able to effectively absorb shock. At this time, the swing amplitude of the connecting arm 302 on the first screw 401 may exceed the compression stroke of the shock-absorbing spring 403, which may cause damage to the shock-absorbing spring 403. By setting the shock-absorbing pad 503, the shock-absorbing spring 403 and the connecting arm 302 can be protected, thereby reducing safety hazards. The second adjusting nut 502 is threadedly connected to the second screw 501. Tightening the second adjusting nut 502 can adjust the relative position of the second adjusting nut 502 on the second screw 501, thereby adjusting the distance between the second adjusting nut 502 and the connecting arm 302, which can adjust the movement stroke of the connecting arm 302, thus providing better protection for elevator cars of different sizes.

[0048] In a further embodiment of this invention, the mounting bracket 1 is provided with reinforcing ribs 105, the positions of which correspond to the positions of the first mounting part 101 and the second mounting part 102.

[0049] In this embodiment, the mounting bracket 1 is integrally cast from aluminum alloy, resulting in a small overall weight and high structural strength. Reinforcing ribs 105 are provided at the corresponding positions of the first mounting part 101 and the second mounting part 102 to further improve the structural strength of the mounting bracket 1.
