Description

Technical Field

[0001] The utility model relates to the technical field of counterweight equipment, in particular to a device for reducing the friction of a counterweight box of a belt conveyor. Background Art

[0002] The heavy hammer type tensioning device is a commonly used tensioning device for long-distance belt conveyors. Figure 1 The counterweight box 1 is often placed between two columns 2. Since the belt itself is elastic, its length changes continuously within a certain range during several processes with large force changes such as no-load starting, loading materials, and unloading and shutdown, causing the counterweight box 1 to float up and down along the columns 2 on both sides.

[0003] The supporting structure of the counterweight box 1 is a baffle 10 with a certain gap. There is sliding friction between the baffle 10 and the column 2. At the same time, the original gap cannot effectively limit the lateral deflection and lateral tilt of the counterweight box 1. During operation, the baffle 10 and the column 2 are scratched and rubbed for a long time, which brings great safety hazards. Utility Model Content

[0004] In order to effectively solve the problems of deflection and lateral tilt of the counterweight box, reduce the collision and friction between the counterweight box and the column, and thus better ensure the safe and efficient operation of the belt running system, the utility model provides a device for reducing the friction of the counterweight box of the belt conveyor.

[0005] The utility model provides a device for reducing friction of a belt conveyor counterweight box, which adopts the following technical solution:

[0006] A device for reducing friction of a counterweight box of a belt conveyor is arranged between the counterweight box and a column, and includes a support seat arranged on the side of the counterweight box close to the column, wherein at least one pair of support seats are arranged obliquely and crosswise and distributed on both sides of the column, and a roller is installed at the end of the support seat close to the column to roll with the column.

[0007] By adopting the above technical solution, when the counterweight box moves up and down, the rollers are in direct contact with the column, and rolling friction occurs. The surrounding rollers can constrain the lateral movement of the counterweight box, and the four degrees of freedom of the counterweight box relative to the column are constrained to one. Compared with the prior art, the utility model converts the sliding friction between the counterweight box and the column into rolling friction, and effectively constrains the travel of the counterweight box, structurally limiting the lateral deflection and tilt of the counterweight box, effectively extending the service life of the column, and thus eliminating equipment safety hazards.

[0008] Optionally, a vertically arranged support seat is also arranged in the middle of the same pair of obliquely cross-arranged support seats.

[0009] By adopting the above technical solution, the rollers on the support seat arranged perpendicular to the side wall of the counterweight box and the rollers on the support seat arranged obliquely work together to limit the lateral displacement of the counterweight box, thereby improving the limiting effect and achieving higher stability.

[0010] Optionally, the support seat is directly fixed to the counterweight box.

[0011] By adopting the above technical solution, the support seat and the counterweight box are directly fixedly connected to facilitate improving the production efficiency.

[0012] Optionally, it also includes a mounting plate, the support seat is fixedly connected to a side of the mounting plate close to the column, and the mounting plate and the counterweight box are connected by bolts.

[0013] By adopting the above technical solution, the design of the mounting plate is convenient for timely disassembly when the roller needs to be replaced.

[0014] Optionally, a positioning box with an open bottom is fixedly connected to the side wall of the counterweight box near the column, and the side wall of the positioning box near the column extends upward from its bottom edge to provide a clearance groove corresponding to the number and position of the support seats. The mounting plate can be removably inserted into the positioning box, and the support seat can be removably clamped in the clearance groove.

[0015] By adopting the above technical solution, the positioning box has a multi-directional limiting effect, and is used in conjunction with bolts to reduce the stress on the bolts. At the same time, the positioning box also reduces the impact of adverse external environments on the connection point between the support seat and the mounting plate.

[0016] Optionally, the roller is a bearing structure.

[0017] By adopting the above technical solution, the use of bearings makes it easier to obtain materials.

[0018] Optionally, the support seat includes two angle steels arranged in parallel, and the roller is rotatably supported between the two angle steels.

[0019] By adopting the above technical solution, angle steel is used to facilitate material acquisition.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] The utility model changes the sliding friction between the counterweight box and the column into rolling friction, and at the same time effectively constrains the travel of the counterweight box, structurally restricts the lateral deflection and tilt of the counterweight box, effectively prolongs the service life of the column, and thus eliminates safety hazards of the equipment;

[0022] The design of the mounting plate allows for easy removal in case the roller needs to be replaced;

[0023] The positioning box has a multi-directional limiting effect. When used with bolts, it reduces the force on the bolts. At the same time, the positioning box also reduces the impact of adverse external environments on the connection points between the support base and the mounting plate.

[0030] The following is combined with Figure 2 -Attached Figure 5 The utility model is described in further detail.

[0031] The utility model embodiment discloses a device for reducing the friction of a counterweight box of a belt conveyor. Example 1

[0032] Reference Figure 2 , the device for reducing the friction of the counterweight box of the belt conveyor includes two groups of support seats 3 fixedly connected to the side wall of the counterweight box 1, and each group of support seats 3 includes three support seats 3 located between the counterweight box 1 and the column 2. The support seat 3 located in the middle is vertically fixed to the side wall of the counterweight box 1, and the two support seats 3 located on the sides are both obliquely fixed to the side wall of the counterweight box 1, and the angle between the two is less than 180°. The support seat 3 in this embodiment includes two parallel angle steels, and a roller 4 is rotatably connected between the two angle steels. The roller 4 in this embodiment is a bearing structure, and other wheel-shaped structures can also be used in other embodiments to meet the use requirements, which is not limited here. The roller 4 is in rolling contact with the column 2, and the three rollers 4 in the same group are distributed in a fan shape.

[0033] The implementation principle of Example 1 is as follows: when the counterweight box 1 moves up and down, the roller 4 is in direct contact with the column 2, and rolling friction occurs. At the same time, the three rollers 4 arranged in a fan shape can constrain the lateral movement of the counterweight box 1, and the four degrees of freedom of the movement of the counterweight box 1 relative to the column 2 are constrained to one. The use of bearings and angle steels can effectively utilize existing resources and reduce production costs. Compared with the prior art, the utility model converts the sliding friction between the counterweight box 1 and the column 2 into rolling friction, and at the same time effectively constrains the travel of the counterweight box 1, structurally limiting the lateral deflection and tilt of the counterweight box 1, effectively extending the service life of the column 2, and thus eliminating equipment safety hazards. Example 2

[0034] Reference Figure 3 After the device has been used for a certain period of time, if the roller 4 is damaged and needs to be replaced, in order to facilitate the replacement of the roller 4, the difference between this embodiment and embodiment 1 is that it also includes a mounting plate 5, the support seat 3 is welded and fixed on the mounting plate 5, and the mounting plate 5 and the counterweight box 1 are connected by multiple bolts 6.

[0035] The implementation principle of Example 2 is as follows: when the roller 4 needs to be replaced, the staff unscrews the bolt 6 to separate the mounting plate 5 from the counterweight box 1, and moves the device vertically upward or downward to remove it. After replacing the new roller 4, the mounting plate 5 can be fixed again with the bolt 6, which is very convenient in operation. Example 3

[0036] Reference Figure 4 and Figure 5 In order to improve the stability of the mounting plate 5 after installation, the difference between this embodiment and embodiment 2 is that a positioning box 7 is fixedly connected to the outer wall of the counterweight box 1, and an opening for the mounting plate 5 to pass through is provided at the bottom of the positioning box 7. Three clearance grooves 70 are provided on the side wall of the positioning box 7 near the column 2 and extend upward from the bottom edge thereof. The positions of the three clearance grooves 70 correspond to the positions of the three support seats 3 one by one, and the clearance grooves 70 are used to clamp and fix the support seats 3. The mounting plate 5 is detachably inserted into the positioning box 7 and connected to the counterweight box 1 by two bolts 6.

[0037] The implementation principle of Example 3 is as follows: when the roller 4 needs to be replaced, the staff first unscrews the two bolts 6, and then pulls the mounting plate 5 downward from the positioning box 7 to complete the disassembly of the mounting plate 5. After replacing the new roller 4, the bolts 6 are used again to fix it. The positioning box 7 can limit the mounting plate 5 in the horizontal direction, and limit the upward movement of the mounting plate 5, while only allowing the mounting plate 5 to move downward. The bolts 6 therein only play a positioning role, reducing the longitudinal and transverse shear forces on the bolts 6, so that a smaller number of bolts 6 can be used, and the stability of the mounting plate 5 after installation is significantly improved. At the same time, the positioning box 7 can also block adverse factors such as wind and rain from the outside, reduce the impact on the welding points of the support seat 3 and the mounting plate 5, and extend the service life.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
