Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly relates to an installation structure of an elevator guide rail. Background Art

[0002] The elevator guide rail is an elevator component composed of a steel rail and a connecting plate, which is divided into a car guide rail and a counterweight guide rail. From the cross-sectional shape, it is divided into three forms: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rail bears the impact force during the car and elevator braking, the impact force during the emergency braking of the safety clamp, etc. The magnitude of these forces is related to the load capacity and speed of the elevator. Therefore, the guide rail should be selected according to the elevator speed and load capacity. Usually, the car guide rail is called the main rail, and the counterweight guide rail is called the secondary rail.

[0003] For example, the application number: CN201720378990.1. The utility model discloses an elevator guide rail, which includes a guide rail body. The guide rail body includes a guiding part, and guiding surfaces made of rigid materials are arranged on both sides of the guiding part; the guide rail body also includes a braking part, and braking surfaces made of flexible materials are arranged on both sides of the braking part. The braking surfaces and the guiding surfaces are parallel to each other, and the width of the braking part does not exceed the width of the guiding part. An installation groove with a front end opening is arranged in the middle of the guiding part, the braking part is installed in the installation groove, and the braking surface is located outside the installation groove. The elevator guide rail in the utility model has elasticity, which helps to reduce vibration and noise during elevator operation; and the surface friction coefficient of the added braking part is much higher than that of the traditional metal guide rail. The guide rail brake can achieve braking with a lower braking torque, realizing that the elevator can also perform brake braking during normal leveling. Its flexible braking surface avoids permanent damage to the guide rail during braking, improving the safety performance of the elevator and the service life of the guide rail.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problems that the guide rail and the guide shoe are in sliding friction, the surface of the guide rail needs to be lubricated with lubricating oil, resulting in insufficient friction between the two, and if there is double-sided contact between the brake and the guide rail, there are high requirements for the alignment between the brake and the guide rail, and at the same time, if there is single-sided contact between the brake and the guide rail, the braking force does not meet the requirements, and due to the installation accuracy, there will be a certain horizontal swing during elevator operation. Therefore, there will be a large gap when the brake brakes, resulting in large operating torque and large noise. However, during the installation of the elevator guide rail in the use process, usually the user needs to hold a level and fit it on the elevator guide rail and use the other hand to support and adjust the elevator guide rail to fit, resulting in too low efficiency for the user to adjust the elevator guide rail for installation with one hand. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in Figures 1 to 3 , an installation structure of an elevator guide rail provided by the present utility model includes an elevator guide rail body 1 and installation holes 2. The installation holes 2 are opened on both sides of the front surface of the elevator guide rail body 1. Clamping plates 3 are arranged on both sides of the front surface of the elevator guide rail body 1. The surface of the elevator guide rail body 1 is in contact with the inner sides of the clamping plates 3. A movable box 4 is arranged at the top of the front surface of the elevator guide rail body 1. The inner wall of the movable box 4 is movably connected to the surface of the clamping plate 3. A bidirectional lead screw 5 is arranged inside the movable box 4. Both sides of the bidirectional lead screw 5 penetrate to both sides of the movable box 4 and are threadedly connected to the inner walls of the clamping plates 3. A placement sleeve 6 is fixedly connected to the right side of the bidirectional lead screw 5. A spirit level 7 is movably connected inside the placement sleeve 6. Limit components 8 are fixedly connected to both sides of the front surface of the clamping plate 3.

[0023] Referring to Figure 2 , the limit component 8 includes a limit block 81. The inner sides of the limit blocks 81 are fixedly connected to both sides of the front surface of the clamping plate 3. Limit grooves 82 are opened on both sides of the front surface of the movable box 4. The inner walls of the limit grooves 82 are slidably connected to the surfaces of the limit blocks 81. The limit blocks 81 are arranged in a T shape.

[0024] As a technical optimization scheme of the present utility model, by setting the limit component 8, during the process of the user rotating the bidirectional lead screw 5, the sliding cooperation between the limit block 81 and the limit groove 82 can be used to limit the up and down movement of the clamping plate 3, avoiding the situation where the clamping plate 3 rotates and cannot move inward smoothly. Then, by setting the limit block 81 in a T shape, the front and back limits of the clamping plate 3 can be carried out, avoiding the situation where the clamping plate 3 is separated from the movable box 4, and improving the use stability.

[0025] Referring to Figure 3 , a magnetic sheet 9 is fixedly connected to the left side of the inner wall of the placement sleeve 6. The right side of the magnetic sheet 9 is magnetically adsorbed to the left side of the spirit level 7.

[0026] As a technical optimization scheme of the present utility model, by setting the magnetic sheet 9, when the user inserts the spirit level 7 into the placement sleeve 6 for placement, the magnetic force of the magnetic sheet 9 can be used to adsorb the left side of the spirit level 7, thereby improving the stability of the spirit level 7 after placement and avoiding the situation where the spirit level 7 slides out of the placement sleeve 6.

[0027] Referring to Figure 2A contact pad 10 is provided on the inner side of the clamping plate 3 , and the clamping plate 3 contacts the elevator guide rail body 1 through the contact pad 10 .

[0028] As a technical optimization solution of the utility model, by providing a contact pad 10, it is convenient for the user to use the clamping plate 3. The clamping plate 3 can contact and clamp the elevator guide rail body 1 through the contact pad 10, which can not only avoid damage to the surface of the elevator guide rail body 1, but also increase the friction between the clamping plate 3 and the elevator guide rail body 1 to avoid slipping and falling.

[0029] refer to Figure 3 A protective pad 11 is fixedly connected to the right side of the magnetic sheet 9, and the protective pad 11 is arranged in a mesh shape.

[0030] As a technical optimization scheme of the utility model, by setting a protective pad 11, the impact force generated when the magnetic sheet 9 uses magnetic force to adsorb the spirit level 7 can be absorbed and buffered by the protective pad 11, preventing the spirit level 7 from being damaged due to excessive impact force. The protective pad 11 is then arranged in a mesh shape so that the protective pad 11 does not affect the magnetic adsorption effect of the magnetic sheet 9 during the protection process.

[0031] refer to Figure 2 The outer side of the contact pad 10 is fixedly connected with a first Velcro 12 , the outer side of the first Velcro 12 is adhered with a second Velcro 14 , and the outer side of the second Velcro 14 is fixedly connected with the inner side of the splint 3 .

[0032] As a technical optimization solution of the utility model, by providing the first Velcro 12 and the second Velcro 14, when the contact pad 10 is damaged after long-term use, the user can directly tear off the contact pad 10 and stick the first Velcro 12 and the second Velcro 14 on the new contact pad 10, so that the new buffer pad can be quickly installed.

[0033] refer to Figure 2 A pull ring 13 is fixedly connected to the right side of the level 7, and the material of the pull ring 13 is PP plastic.

[0034] As a technical optimization solution of the utility model, by providing a pull ring 13, when the user needs to take out the spirit level 7, the user can pull the pull ring 13 to the right to drive the spirit level 7 to be taken out, giving the user a point of force for applying, and taking advantage of the low cost of PP plastic, the cost of use is reduced.

[0035] Working principle and usage process of the present utility model: When the user needs to install the elevator guide rail body 1, the user can make the back surface of the movable box 4 fit with the front surface of the elevator guide rail body 1. Then the user rotates the bidirectional lead screw 5. By using the threaded connection between the bidirectional lead screw 5 and the clamping plate 3, the bidirectional lead screw 5 drives the clamping plate 3 to move inward and clamp on the front surface of the elevator guide rail body 1. Then the user can directly insert the level 7 into the placement sleeve 6. Then the user can free both hands to adjust the installation inclination of the elevator guide rail body 1. At the same time, the user can also observe the horizontal detection data on the level 7. During the process of the user rotating the bidirectional lead screw 5, the sliding fit between the limit block 81 and the limit groove 82 can limit the up and down movement of the clamping plate 3, avoiding the situation that the clamping plate 3 rotates and cannot move inward smoothly. By setting the limit block 81 in a T shape, the front and back limits of the clamping plate 3 can be achieved, avoiding the situation that the clamping plate 3 detaches from the movable box 4, improving the use stability and having the ability to facilitate auxiliary installation.

[0036] In summary: For the installation structure of this elevator guide rail, by setting the bidirectional lead screw 5, rotating the bidirectional lead screw 5 drives the clamping plate 3 to move inward and clamp on the front surface of the elevator guide rail body 1. Then the user can directly insert the level 7 into the placement sleeve 6. Then the user can free both hands to adjust the installation inclination of the elevator guide rail body 1. At the same time, the user can also observe the horizontal detection data on the level 7, solving the problem that when installing the elevator guide rail, usually the user still needs to hold the level against the elevator guide rail with one hand and use the other hand to support the elevator guide rail for fitting and adjustment, resulting in too low efficiency of the user adjusting the elevator guide rail for installation with one hand.
