Description
Technical Field
[0001] This utility model relates to the field of brake shoe riveting technology, and more specifically, to a device for riveting brake shoes of electric shovels that push and press against dead brakes and smooth wheel brakes. Background Technology
[0002] The WK-4 electric shovel is a single-blade, forward-shovel, tracked, full-rotation electric excavator primarily used in mining, capable of efficiently excavating and transporting ore or rock. Due to the harsh operating environment of electric shovels, the components of the pushing mechanism bear a heavy load, especially the brake wheel and the push motor polished wheel, which are the main load-bearing parts of the pushing mechanism. The brake shoe frame is the main component of the pushing braking system, and is prone to wear and damage due to the high-speed rotation of the brake wheel and the push motor polished wheel.
[0003] In existing technologies, the riveting operation of brake pads and brake shoe frames is mostly carried out on a bench vise. Due to the inconsistency between the curvature of the bench vise and the curvature of the brake shoe frame, the brake pads cannot be tightly fitted onto the brake shoe frame. Consequently, the rivets are not easy to tighten during riveting, and the brake pads are prone to breakage after a period of use. In some cases, the brake pads may even fall off along with the rivets, ultimately requiring frequent replacement of brake shoes and causing the electric shovel to stop working, which seriously affects production.
[0004] In summary, how to solve the problem of poor fit between the brake pads and brake shoe frame when installing them on a bench vise, and the lack of tightness during riveting, which leads to easy breakage of the brake pads and easy detachment along with the rivets, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a device for riveting electric shovels to push and press the brake shoes of the dead brake and the light wheel brake. It has high responsiveness, is convenient and quick to use, and can ensure that the brake shoes and brake shoe frame fit tightly and the rivets are secure, avoiding the problems of brake shoes breaking or brake shoes falling off together with the rivets.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A device for riveting electric shovels to push and press the brake shoes of deadbolt brakes and smooth wheel brakes, comprising:
[0008] The activity platform can move along the ground;
[0009] A dead-hold brake wheel includes an arc-shaped portion and a support portion horizontally located below the arc-shaped portion. The support portion is disposed on the movable platform. The arc-shaped portion has at least two notches spaced apart circumferentially, and the notches are used for installing rivets.
[0010] The push motor roller is mounted on the movable platform, and the push motor roller and the dead brake roller are distributed in parallel.
[0011] In one embodiment, the support is welded to the movable platform.
[0012] In one embodiment, the push motor optical wheel is welded to the movable platform.
[0013] In one embodiment, one side of the arcuate portion is cut with notches of different sizes, the notches corresponding to the rivet hole locations of the brake shoe frame.
[0014] In one embodiment, a baffle is provided on the other side of the arcuate portion.
[0015] In one embodiment, the baffle is welded onto the arc-shaped portion.
[0016] In one embodiment, the movable platform includes a rectangular steel plate and omnidirectional wheels rotatably disposed at the four corners of the steel plate.
[0017] In one embodiment, the caster wheel includes a rubber component.
[0018] In one embodiment, both the dead-hold brake wheel and the push motor impeller are scrapped structural components.
[0019] When using the device provided by this utility model for riveting electric shovels to push the brake shoes of deadbolt brakes and smooth wheel brakes, firstly, the operator can cut the brake shoes to a size that matches the length and width of the brake shoe frame. Then, place the brake shoes on the side of the deadbolt brake wheel with the notch. Next, place the brake shoe frame on the brake shoes and use an electric drill to drill holes downwards from the rivet holes in the brake shoe frame. The electric drill can drill through holes in the brake shoes that align with the rivet holes and penetrate the brake shoes. Then, the operator inserts rivets through the rivet holes and through holes, and can perform the initial installation of rivets sequentially from the middle of the brake shoes to both sides. Finally, the operator can move the initially fixed brake shoe frame and brake shoes onto the smooth wheel of the pushing motor, and then perform the riveting and tightening operations sequentially. Moreover, because the top of the motor smooth wheel and the bottom of the brake shoes match in curvature, the initially fixed rivets can be prevented from shifting, ensuring that the rivets are fixed in the required position, resulting in a tight fit between the brake shoes and the brake shoe frame. In addition, because this device is equipped with a movable platform, it can be moved according to actual needs, improving the device's responsiveness and making it easier to meet the user's needs.
[0020] In summary, the device provided by this utility model for riveting electric shovels to push the brake shoes of the dead brake and the light wheel brake has high responsiveness and is convenient and quick to use. It can ensure that the brake shoes and the brake shoe frame fit tightly and that the rivets are firmly fastened, avoiding the problems of brake shoes breaking or brake shoes falling off along with the rivets.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The core of this utility model is to provide a device for riveting electric shovels to push and press the brake shoes of dead brakes and light wheel brakes. It has high responsiveness, is convenient and quick to use, and can ensure that the brake shoes and brake shoe frame fit tightly and the rivets are secure, avoiding the problems of brake shoes breaking or brake shoes falling off together with rivets.
[0029] like Figure 3 As shown, this specific embodiment provides a device for riveting electric shovels to push and press the brake shoes of the deadbolt brake and the smooth wheel brake, comprising:
[0030] Activity platform 2, which can move along the ground;
[0031] The brake wheel 3 includes an arc-shaped part 31 and a support part 32 located horizontally below the arc-shaped part 31. The support part 32 is provided on the movable platform 2. The arc-shaped part 31 is provided with at least two notches 4 at intervals along the circumference. The notches 4 are used to install rivets.
[0032] The push motor roller 6 is located on the movable platform 2, and the push motor roller 6 and the dead brake roller 3 are distributed in parallel.
[0033] It should be noted that this device solves the problem of poor fit and loose riveting between the brake pads and brake shoe brackets when installing them on a bench vise, thus ensuring the performance of the brake shoe brackets. Furthermore, this device is suitable not only for riveting brake pads and brake shoe brackets in factory buildings but also for riveting brake pads and brake shoe brackets on-site with electric shovels in mining areas. In practical applications, the shape, structure, size, material, and position of the movable platform 2, the dead-hold brake wheel 3, and the push-press motor smooth wheel 6 can be determined according to the actual situation and requirements.
[0034] When using the device provided by this utility model for riveting electric shovels to push the brake shoes of the deadbolt brake and the brake shoe with a smooth wheel, the operator first cuts the brake shoe to a size that matches the length and width of the brake shoe frame. Then, the brake shoe is placed on the side of the deadbolt brake wheel 3 with the notch 4. Next, the brake shoe frame is placed on the brake shoe, and a hole is drilled downwards from the rivet hole of the brake shoe frame using an electric drill. The electric drill can drill through holes in the brake shoe that are aligned with the rivet holes and drill through the brake shoe. Afterwards, the operator inserts rivets through the rivet holes and through holes, and can perform the initial installation of rivets sequentially from the middle of the brake shoe to both sides. Finally, the operator can move the initially fixed brake shoe frame and brake shoe onto the pushing motor smooth wheel 6, and then perform the riveting and tightening operation sequentially. Moreover, since the top of the motor smooth wheel 6 and the bottom curvature of the brake shoe match, the initially fixed rivets can be prevented from shifting, ensuring that the rivets are fixed in the required position, so that the brake shoe and brake shoe frame fit tightly. In addition, since this device is equipped with a movable platform 2, the device can be moved according to actual needs, improving the device's responsiveness and making it easier to meet the user's needs.
[0035] In summary, the device provided by this utility model for riveting electric shovels to push the brake shoes of the dead brake and the light wheel brake has high responsiveness and is convenient and quick to use. It can ensure that the brake shoes and the brake shoe frame fit tightly and that the rivets are firmly fastened, avoiding the problems of brake shoes breaking or brake shoes falling off along with the rivets.
[0036] In one embodiment, the support portion 32 is welded onto the movable platform 2.
[0037] It should be noted that the dead-hold brake wheel 3 includes an arc-shaped part 31 and a support part 32 located horizontally below the arc-shaped part 31. This can refer to cutting off 1 / 3 of the structure of the old dead-hold brake wheel 3 to obtain the horizontally distributed support part 32, and then welding the support part 32 onto the movable platform 2. Moreover, the top of the old dead-hold brake wheel 3 is the arc-shaped part 31.
[0038] In one embodiment, such as Figure 3As shown, the push motor roller 6 is welded onto the movable platform 2. The push motor roller 6 is used to rivet the initially installed brake pads and brake shoe frame.
[0039] In one embodiment, one side of the arc-shaped portion 31 is cut with notches 4 of different sizes, the notches 4 corresponding to the rivet hole locations of the brake shoe frame. The notches 4 are set to different sizes to make the device applicable to brake shoe frames of different sizes, thereby improving the applicability of the device.
[0040] In one embodiment, a baffle 5 is provided on the other side of the arcuate portion 31. For example, the steel plate is configured as a sheet material structure with a length of 100 mm, a width of 120 mm, and a thickness of 20 mm.
[0041] It should be noted that the brake pad is placed on the side of the brake wheel 3 with the notch 4, and the brake shoe bracket is placed on the brake pad. Moreover, one side of the brake pad and the brake shoe bracket can be blocked by the baffle 5 to prevent the brake pad or brake shoe bracket from falling off the arc-shaped part 31 during the subsequent drilling of the brake shoe bracket through the rivet hole. The electric drill can drill through the brake pad with a through hole aligned with the rivet hole and drill through the brake pad.
[0042] In one embodiment, the baffle 5 is welded onto the arc-shaped portion 31 to ensure that the baffle 5 will not separate or fall off during use, which helps to simplify the assembly operation of the device and improve the service life of the device.
[0043] In one embodiment, the movable platform 2 includes a rectangular steel plate and casters 1 rotatably disposed at the four corners of the steel plate. For example, the steel plate can be configured as a plate structure with a length of 600mm, a width of 500mm, and a thickness of 16mm, and four caster seats are welded to the bottom of the four corners of the steel plate. Each caster seat and the caster 1 are hinged by a pivot, so that the caster 1 can rotate 360°, which facilitates the control of the movable platform 2 for movement.
[0044] In one embodiment, the caster wheel 1 includes a rubber component. The rubber component provides good cushioning and shock absorption while also being able to withstand a certain load. Of course, the caster wheel 1 can also be made of other types of materials depending on actual needs and circumstances.
[0045] In one embodiment, both the dead-hold brake wheel 3 and the push motor roller 6 are scrapped structural parts. That is, the old and discarded dead-hold brake wheel can be used as the dead-hold brake wheel 3 of this application (the bottom of the old dead-hold brake wheel needs to be cut off so that it is horizontally set on the movable platform 2), and the old and discarded push motor roller can be used as the push motor roller 6 of this application, so as to achieve the effect of waste utilization and reducing the manufacturing cost of the device.
[0046] To further illustrate the device provided by this utility model for riveting electric shovels to push and press the brake shoes of the dead brake and the light wheel brake, the following example is given.
[0047] 1. For example Figure 1 As shown, the bottom of the movable platform 2 is equipped with four 5-inch casters 1 as movable feet. The caster seats can be welded to the bottom of the steel plate, and the casters 1 and the caster seats are hinged to make the movable platform 2 a movable base.
[0048] 2. For example Figure 2 As shown, after cutting off 1 / 3 of the old dead-hold brake wheel 3, it is welded onto the steel plate of the movable platform 2. Different sizes of notches 4 are cut on the dead-hold brake wheel 3 according to the rivet hole position of the brake shoe frame to facilitate the installation of rivets. A baffle 5 is welded on the other side of the dead-hold brake wheel 3 where no hole is made.
[0049] 3. For example Figure 3 As shown, the waste pusher motor smooth wheel 6 is welded to the side near the baffle 5 to complete the assembly operation of this device;
[0050] 4. Cut the brake pads to the size that matches the length and width of the brake shoe frame. Place the brake pads on the side of the brake wheel 3 with the notch 4, and then place the brake shoe frame on the brake pads. Use an electric drill to drill holes downward from the rivet holes of the brake shoe frame. The electric drill can drill through holes in the brake pads that are aligned with the rivet holes and drill through the brake pads. Then, insert the rivets through the rivet holes and the through holes. The initial installation of the rivets can be carried out from the middle of the brake pads to both sides.
[0051] 5. Move the initially fixed brake shoe frame and brake pads onto the push motor roller 6, and then rivet and tighten the rivets in sequence.
[0052] This device solves the problem of brake pads and brake shoe frames being prone to loosening and rivets falling off when installing them on a bench vise. It is suitable for riveting brake shoe frames anywhere, such as in factories and electric shovels. This device has high responsiveness and is easy and quick to operate. It can ensure that the brake pads and brake shoe frames fit tightly and the rivets are secure, reducing the occurrence of brake pad breakage and rivet falling off, and helping to improve the safety and reliability of the device.
