Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ground maintenance, and in particular to the chassis control structure applied to an integrated stone maintenance machine. Background Technology
[0002] Stone floors will experience varying degrees of wear and tear after prolonged use. Wear and tear not only affects the appearance, but if left unattended for a long time, it may also cause the floor to crack. Therefore, regular maintenance is necessary. During the maintenance process, the worn floor should first be polished, and then a repair and sealing layer should be applied.
[0003] Existing equipment for maintaining stone floors, such as stone renovation and maintenance machines, includes a frame and a chassis that slides on the frame. In existing technologies, the lifting and lowering of the chassis is mostly directly controlled by cylinders or linear motors. However, in actual use, it has been found that the force generated by the grinding disc installed on the chassis during operation is fed back to the equipment used to control the lifting and lowering of the chassis. After long-term use, this will affect the service life of the equipment used to control the lifting and lowering of the chassis. Utility Model Content
[0004] In order to ensure the service life of the equipment used to control the lifting of the chassis, this application provides a chassis control structure for use in an integrated stone maintenance machine.
[0005] The chassis control structure for the integrated stone maintenance machine provided in this application adopts the following technical solution:
[0006] A chassis control structure for an integrated stone maintenance machine is used to control the sliding of the chassis body. It includes a frame and a push rod motor mounted on the frame. A chain is mounted on the piston rod of the push rod motor. The end of the chain away from the piston rod of the push rod motor is connected to the chassis body. The chassis body is provided with a fixing member for fixing the chain. Counterweights are symmetrically arranged on both sides of the fixing member. The counterweights are mounted on the chassis body.
[0007] By adopting the above technical solution, the lifting and lowering of the chassis body is controlled by the cooperation of the push rod motor and the chain. The counterweight provides pressure to the chassis body, ensuring that the chassis body remains in contact with the ground during operation, thereby guaranteeing the working quality of the integrated stone maintenance machine. Since the push rod motor and the chassis body are connected by a chain, the force generated by the grinding disc installed on the chassis body during operation is unlikely to affect the push rod motor, effectively ensuring the service life of the equipment used to control the lifting and lowering of the chassis body. The pressure of the chassis body on the stone floor can be controlled by controlling the extension and retraction of the piston rod of the push rod motor, thus making the stone maintenance machine suitable for different types of stone floors and expanding its applicability.
[0008] Preferably, tie rods are symmetrically arranged on both sides of the center of gravity of the chassis body, and a control plate for mounting the tie rods is provided on the chassis body. One end of the tie rod is rotatably connected to the control plate, and the other end of the tie rod is rotatably connected to the frame.
[0009] By adopting the above technical solution and setting the pull rod, the swing amplitude of the chassis body is limited, thereby improving the stability of the chassis body when it is raised and lowered under the action of the push rod motor. During the raising and lowering process of the chassis body, it is not easy to collide and be damaged with other structures, thus ensuring the service life of the integrated stone maintenance machine to a certain extent.
[0010] Preferably, a limiting cylinder is rotatably connected to the frame, the outer diameter of the limiting cylinder increases sequentially in the direction toward both ends of the limiting cylinder, and the chain is in contact with the outer wall of the limiting cylinder.
[0011] By adopting the above technical solution, the limiting cylinder is used to guide and position the chain, improving the reliability of the chassis body lifting and lowering through the chain when the push rod motor starts and closes. The setting of the limiting cylinder and the frame rotating connection reduces the friction between the chain and the limiting cylinder, reducing the noise when the chassis body is lifted and lowered while ensuring service life.
[0012] Preferably, a fixing bolt is provided at the end of the chain away from the piston rod, and a fixing through hole is provided on the chassis body for the fixing bolt to pass through. A fixing nut is threaded onto the fixing bolt, and the fixing bolt and the fixing nut cooperate to install the chain on the chassis body.
[0013] By adopting the above technical solution, the combination of fixing bolts and fixing nuts effectively ensures the reliability of the chain and chassis body fixing, and makes the chassis body and chain detachable. In actual application, wear parts can be replaced individually.
[0014] Preferably, the chassis body is provided with a water-retaining skirt, and the chassis body can be moved by the push rod motor until the water-retaining skirt contacts the ground.
[0015] By adopting the above technical solution and setting up the water-retaining skirt, the generation of dust and splashes can be effectively reduced. This not only protects the safety of operators and reduces environmental pollution, but also reduces the time spent on work interruption due to cleaning dust and splashes, thus improving the efficiency of stone floor grinding and maintenance.
[0016] Preferably, the water-retaining skirt is provided with a mounting plate, the chassis body is provided with mounting bolts, the mounting bolts are threaded with mounting buttons, the mounting plate is provided with a through hole for the mounting bolts to pass through, and the mounting plate is attached to the chassis body by the mounting buttons.
[0017] By adopting the above technical solution, the mounting plate and mounting button work together to make the water-retaining skirt detachably fixed to the chassis body, which facilitates the replacement of worn water-retaining skirts.
[0018] Preferably, a support strip is provided in the middle of the water-blocking skirt.
[0019] By adopting the above technical solution, the support strip is used to support the water-blocking skirt, making the water-blocking skirt less prone to deformation during actual use and improving the reliability of blocking dust and splashes through the water-blocking skirt.
[0020] Preferably, there are multiple water-blocking skirts. In two adjacent water-blocking skirts, one of the water-blocking skirts is rotatably connected with a fastening ring, and the other water-blocking skirt is provided with a fastening block that cooperates with the fastening ring. Both the fastening block and the fastening ring are provided on the support strip.
[0021] By adopting the above technical solution, the fastening ring and the fastening block cooperate to fix two adjacent water-blocking skirts, effectively reducing the gap between the two adjacent water-blocking skirts and improving the reliability of reducing dust and splashes through the water-blocking skirts.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The push rod motor is connected to the chassis body by a chain. The force generated by the grinding disc mounted on the chassis body during operation is not likely to affect the push rod motor, effectively ensuring the service life of the equipment used to control the lifting of the chassis.
[0024] 2. The pressure of the chassis body on the stone floor can be controlled by extending and retracting the piston rod of the push rod motor, thus making the stone maintenance machine suitable for different types of stone floors and expanding the applicability of the integrated stone maintenance machine.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.
[0032] This application discloses a chassis control structure for an integrated stone maintenance machine, referring to... Figure 1 and Figure 2 The drivable stone maintenance integrated machine, used to control the sliding of the chassis body 1, includes a frame 2 and a push rod motor 3 mounted on the frame 2. A chain 4 is fixed to the piston rod of the push rod motor 3, and one end of the chain 4 away from the piston rod of the push rod motor 3 is fixed to the chassis body 1. The chassis body 1 is provided with a fixing member for fixing the chain 4. Counterweights 11 are symmetrically arranged on both sides of the fixing member and are fixed to the chassis body 1.
[0033] The lifting and lowering of the chassis body 1 is controlled by the cooperation of the push rod motor 3 and the chain 4. The counterweight 11 is used to provide pressure to the chassis body 1, so that the grinding disc on the chassis body 1 can remain in contact with the ground during operation, thereby ensuring the working quality of the integrated stone maintenance machine. Since the push rod motor 3 and the chassis body 1 are connected by the chain 4, the force generated by the grinding disc installed on the chassis body 1 during operation is not likely to affect the push rod motor 3, effectively ensuring the service life of the equipment used to control the lifting and lowering of the chassis body 1. The pressure of the chassis body 1 on the stone floor can be controlled by controlling the extension and retraction of the piston rod of the push rod motor 3, so that the stone maintenance machine can be applied to different stone floors, thus improving the applicability of the integrated stone maintenance machine.
[0034] Reference Figure 1 and Figure 2 A limiting cylinder 21 is rotatably connected to the frame 2, so that the outer diameter of the limiting cylinder 21 increases sequentially in the direction towards both ends of the limiting cylinder 21, thus the limiting cylinder 21 is set in a funnel shape. The chain 4 is in contact with the outer wall of the limiting cylinder 21 and the chain 4 is located in the middle of the limiting cylinder 21. The limiting cylinder 21 is used to guide and position the chain 4, improving the reliability of the chassis body 1 being raised and lowered by the chain 4 when the push rod motor 3 is opened and closed. The setting of the limiting cylinder 21 being rotatably connected to the frame 2 reduces the friction between the chain 4 and the limiting cylinder 21, and reduces the noise when the chassis body 1 is raised and lowered while ensuring service life.
[0035] Reference Figure 2 The chassis body 1 has symmetrical tie rods 12 on both sides of its center of gravity. A control plate 13 for mounting the tie rods 12 is welded and fixed on the chassis body 1. One end of the tie rod 12 is rotatably connected to the control plate 13, and the other end of the tie rod 12 is rotatably connected to the frame 2. By setting the tie rods 12, the swing amplitude of the chassis body 1 is limited, thereby improving the stability of the chassis body 1 when it is raised and lowered under the action of the push rod motor 3. During the raising and lowering process of the chassis body 1, it is not easy to collide with other structures and be damaged, thus ensuring the service life of the integrated stone maintenance machine to a certain extent.
[0036] Reference Figure 1 and Figure 3 A fixing bolt 41 is welded and fixed to the end of the chain 4 away from the piston rod. A fixing through hole 14 is opened on the chassis body 1 for the fixing bolt 41 to pass through. A fixing nut 42 is threaded onto the fixing bolt 41. The fixing nut 42 cooperates with the fixing bolt 41 to fix the chain 4 to the chassis body 1. Through the cooperation of the fixing bolt 41 and the fixing nut 42, on the one hand, the reliability of the fixing of the chain 4 to the chassis body 1 is effectively guaranteed, and on the other hand, the chassis body 1 and the chain 4 are detachably connected. In actual application, worn parts can be replaced individually.
[0037] Reference Figure 2 and Figure 4 The chassis body 1 is equipped with a water-retaining skirt 15, which can be made of rubber. The chassis body 1 can move to the point where the water-retaining skirt 15 contacts the ground under the action of the push rod motor 3. During the process of grinding and maintaining the stone floor with the integrated stone maintenance machine, a large amount of dust and splashes will be generated. These dust and splashes may cause damage to the operator's eyes, skin and respiratory tract. The water-retaining skirt 15 can effectively reduce the generation of dust and splashes, which can not only protect the safety of the operator and reduce environmental pollution, but also reduce the time of work interruption due to cleaning dust and splashes, and improve the efficiency of grinding and maintaining the stone floor.
[0038] Reference Figure 2 and Figure 4The water-retaining skirt 15 is equipped with a rigid mounting plate 151. Mounting bolts 16 are welded and fixed to the chassis body 1, and mounting buttons 161 are threaded onto the mounting bolts 16. A through hole is provided on the mounting plate 151 for the mounting bolts 16 to pass through. The mounting plate 151 is attached to the chassis body 1 via the mounting buttons 161, allowing the water-retaining skirt 15 to be detachably fixed to the chassis body 1, facilitating replacement of worn water-retaining skirts 15. A support strip 152, made of iron sheet, is provided in the middle of the water-retaining skirt 15. The support strip 152 provides support for the water-retaining skirt 15, preventing deformation during actual use and improving the reliability of the water-retaining skirt 15 in blocking dust and splashes.
[0039] Reference Figure 4 There are multiple water-blocking skirts 15, and the number of water-blocking skirts 15 depends on the size and shape of the chassis body 1. In this embodiment, there are four water-blocking skirts 15. The four water-blocking skirts 15 work together to surround the chassis body 1. In two adjacent water-blocking skirts 15, a fastening ring 153 is rotatably connected to the support strip 152 of one water-blocking skirt 15, and a fastening block 154 that cooperates with the fastening ring 153 is fixed on the support strip 152 of the other water-blocking skirt 15. When the fastening ring 153 rotates until the fastening block 154 is embedded in the fastening ring 153, the two adjacent water-blocking skirts 15 are fixed, effectively reducing the gap between the two adjacent water-blocking skirts 15.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
