Description

Technical Field

[0001] This application belongs to the field of workpiece assembly technology, and specifically relates to an anti-trampling device for workpiece assembly. Background Technology

[0002] Currently, during excavator assembly, after the valve block is installed, operators still need to stand on the valve block to perform assembly work, such as directly stepping on the valve block and its hydraulic pipes. Under these direct-stepping conditions, due to the relatively low tightening torque of the hydraulic pipes, some hydraulic pipes become loose after being stepped on, and the additional tightening torque on some hydraulic joints leads to damage to the connecting threads and oil leaks. Furthermore, the operator wearing non-slip socks and directly stepping on the hydraulic pipes creates a harsh working environment, making prolonged operation impossible. Summary of the Invention

[0003] The purpose of this application is to provide an anti-trampling device for workpiece assembly, so as to prevent damage to other parts on the workpiece due to direct trampling, and to ensure the operator's long-term operation.

[0004] To achieve the above objectives, this application provides an anti-trampling device for workpiece assembly. The workpiece is mounted on a workpiece mounting component, and the anti-trampling device includes:

[0005] A foot pedal has a foot surface for the operator to step on; and a component installed on the side of the foot pedal opposite to the foot surface:

[0006] Support and positioning components are positioned and supported on the workpiece.

[0007] The snap-fit ​​components, snap-fit ​​components, and support positioning components are arranged at intervals along the length of the pedal; and

[0008] The drive assembly is connected to the snap-fit ​​drive and is capable of driving the snap-fit ​​to swing so that the snap-fit ​​engages or disengages from the side of the workpiece mounting.

[0009] In some embodiments, the pedal has two vertical plates spaced apart along its length. The locking component includes a horizontal rotating plate and a vertical locking plate that are vertically connected. The drive assembly is located between the two vertical plates and connected to the horizontal rotating plate. The horizontal rotating plate is rotatably connected between the two vertical plates. The end of the vertical locking plate opposite to the horizontal rotating plate has a latching part.

[0010] In some implementations, there are multiple latching parts, and these multiple latching parts are located on horizontal planes at different heights.

[0011] In some implementations, the driving component includes:

[0012] The guide rod can move along the height direction and pass through the pedal; and

[0013] An elastic element is wound around the outer periphery of the guide rod and connected between the bottom surface of the transverse rotating plate and the pedal.

[0014] In some embodiments, the guide rod is further provided with a first locking member and a second locking member. The first locking member is used to lock the guide rod and the pedal. The second locking member is located below the transverse rotating plate and is fixedly connected to the guide rod. The anti-stepping device also includes a pressing assembly connected to the second locking member. One end of the pressing assembly is hinged to the second locking member, and the other end extends from below the vertical plate to the outside and can press against the surface of the workpiece mounting part.

[0015] In some embodiments, the clamping assembly includes two clamping blocks, the two clamping blocks abutting against the surface of the workpiece mounting at different horizontal heights.

[0016] In some embodiments, the end of the clamping block that abuts against the workpiece mounting component has a guide inclined surface.

[0017] In some embodiments, the second locking member includes a bushing and a mounting portion extending outward from the bushing. The bushing is fixedly sleeved on the outer periphery of the guide rod. A through-hole extending in the height direction is provided on the vertical plate. One end of the mounting portion away from the bushing is inserted into the through-hole and can move in the height direction. The clamping block is hinged to the side of the mounting portion.

[0018] In some embodiments, the pedal is further provided with a side plate extending along the length direction, and a guide hole extending along the length direction is provided on the side plate. The support positioning member and the guide hole are respectively located at both ends of the pedal along the width direction. The anti-pedaling device also includes a guide shaft, one end of which is connected to the support positioning member, and the other end is slidably inserted into the guide hole.

[0019] In some embodiments, the support positioning element is a block structure with notches at the ends for engaging with the workpiece.

[0020] Through the above technical solution, the anti-trampling device provided by the embodiments of the present invention has the following beneficial effects:

[0021] Compared to existing technologies where operators directly step on the workpiece surface for assembly work, this application provides an anti-stepping device above the workpiece. This device is supported and positioned at a suitable location on the workpiece by a support and positioning component, ensuring the foot pedal is positioned above the workpiece. A drive assembly then drives a snap-fit ​​component to snap into place on the side of the workpiece mounting component, thus stably supporting the foot pedal on the workpiece mounting component for operator use. This application employs two snap-fit ​​structures to place the entire anti-stepping device on the workpiece mounting component, preventing operators from stepping directly on the valve block during operation and avoiding potential hydraulic pipe leakage issues caused by direct stepping on the hydraulic pipes.

[0028] Detailed Implementation

[0029] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0030] The following description, with reference to the accompanying drawings, describes an anti-trampling device for workpiece assembly according to this application.

[0031] like Figure 1 As shown, this application proposes an anti-trampling device for assembling workpiece 5. Workpiece 5 is disposed on workpiece mounting part 6. The anti-trampling device includes a foot pedal 1 and a support positioning part 2, a snap-fit ​​part 3, and a drive assembly installed on the side of the foot pedal 1 away from the foot surface. The foot pedal 1 has a foot surface for the operator to step on. The support positioning part 2 is positioned and supported on the workpiece 5. The snap-fit ​​part 3 and the support positioning part 2 are arranged at intervals along the length direction of the foot pedal 1. The drive assembly is driven to the snap-fit ​​part 3 and can drive the snap-fit ​​part 3 to swing so that the snap-fit ​​part 3 snaps into or disengages from the side of the workpiece mounting part 6.

[0032] In this application, the workpiece 5 can be a valve block used in the excavator assembly process. The valve block is installed on a valve block mounting component. After the valve block is installed, the operator can stand on the anti-trampling device of this application to perform assembly work on other components of the valve block. Of course, this anti-trampling device can also be applied to other scenarios where it is necessary to prevent trampling during the assembly of workpiece 5, and is not limited here.

[0033] When assembling workpiece 5, the operator places the anti-trampling device on the support surface of the workpiece mounting part 6. The operator needs to stand on the foot pedal 1 during assembly; therefore, before standing, the foot surface of the foot pedal 1 needs to be flat enough for the operator to stand comfortably, ensuring safety. Specifically, first, the positioning support is positioned at a suitable location on workpiece 5 and fixed to the surface of workpiece 5. Then, based on the curvature of the support surface of workpiece mounting part 6, the drive assembly drives the snap-fit ​​part 3 to swing towards the surface of workpiece mounting part 6, so that the snap-fit ​​part 3 snaps into the side of workpiece mounting part 6, thereby fixing the other end of the foot pedal 1. This application uses two snap-fit ​​structures to place the entire anti-trampling device on the workpiece mounting part 6, preventing the operator from stepping on the valve block during operation, thus avoiding the quality hazard of oil leakage from the hydraulic pipes on the valve block due to direct stepping on the hydraulic pipes. Furthermore, because the foot surface of the foot pedal 1 is flat and wide, it is suitable for operators to stand for extended periods, improving operator safety.

[0034] It is important to note that, such as Figure 1 As shown, since the entire pedal 1 has a certain length, in order to ensure the stability of the pedal 1 during the stepping process, the positioning support and the snap-fit ​​3 need to be arranged at intervals. The distance between the two should be at least greater than or equal to half the length of the pedal 1 in order to prevent the pedal 1 from tipping over during the stepping process.

[0035] In some embodiments, the foot pedal 1 has two vertical plates 11 spaced apart along its length, forming a receiving space between the two vertical plates 11 for inserting the snap-fit ​​member 3. The snap-fit ​​member 3 includes a horizontal rotating plate 31 and a vertical snap-fit ​​plate 32 connected vertically. A drive assembly is disposed between the two vertical plates 11 and connected to the horizontal rotating plate 31. The horizontal rotating plate 31 is rotatably connected between the two vertical plates 11 via a snap-fit ​​shaft. The end of the vertical snap-fit ​​plate 32 facing away from the horizontal rotating plate 31 has a latching part 33.

[0036] The vertical locking plate 32 includes two locking posts spaced apart in the left-right direction and a connecting rod connecting the two locking posts. The two locking posts have different heights, and each locking post has a latching part 33 at its bottom end that engages with the side of the workpiece mounting part 6. Since the supporting surface of a typical workpiece mounting part 6 usually has a certain curvature, in order to adapt to the side end face of the curved surface, the horizontal planes where the two latching parts 33 are located need to be at different heights to engage different positions on a curved segment.

[0037] In some embodiments, the number of latching parts 33 is multiple, and the multiple latching parts 33 are located on horizontal planes at different heights. Of course, the number of latching parts 33 in this application is not limited to... Figure 1 and Figure 2 The two shown can also be more than two. Multiple snap-fit ​​parts 33 can ensure a more stable snap-fit ​​on the arc-shaped side of the workpiece mounting part 6.

[0038] In some embodiments, the drive assembly includes a guide rod 41 and an elastic element 42; the guide rod 41 is movable in the height direction and passes through the pedal 1; the elastic element 42 is arranged around the outer periphery of the guide rod 41 and connected between the transverse rotating plate 31 and the bottom surface of the pedal 1. The elastic element 42 may be a spring.

[0039] In some embodiments, the guide rod 41 is further provided with a first locking member 43 and a second locking member 44. The first locking member 43 is used to lock the guide rod 41 and the foot pedal 1. The second locking member is located below the transverse rotating plate 31 and is fixedly connected to the guide rod 41. The anti-stepping device also includes a pressing assembly. One end of the pressing assembly is hinged to the second locking member, and the other end extends from below the vertical plate 11 to the outside and can press against the surface of the workpiece mounting member 6.

[0040] Connecting holes are provided at opposite positions on both vertical plates 11, and a through hole is provided on the horizontal rotating plate 31 for the guide rod 41 to pass through. The bottom end of the elastic element 42 is connected to the outer periphery of the through hole. As the second locking element moves upward with the guide rod 41, it can apply an upward pushing force to the horizontal rotating plate 31 when it contacts it, thereby changing the distance between the horizontal rotating plate 31 and the foot pedal 1, which causes the elastic element 42 to have a certain elastic deformation. When the guide rod 41 moves downward, the elastic element 42 applies a downward pushing force to the horizontal rotating plate 31 during the process of restoring its deformation, which allows the vertical locking plate 32 to swing in a direction away from the workpiece mounting part 6.

[0041] As the guide rod 41 extends upward along the height direction and moves the pedal 1, it can drive the second locking member below the transverse rotating plate 31 to move upward along with the guide rod 41. The second locking member applies an upward pushing force to the bottom surface of the transverse rotating plate 31. At this time, the transverse rotating plate 31 tightens upward under the action of the pushing force, and the elastic member 42 has a certain compression deformation, which in turn drives the vertical snap plate 32 to swing around the snap plate axis toward the direction close to the workpiece mounting part 6 until the snap-on part 33 on the vertical snap plate 32 snaps into the side of the workpiece mounting part 6. At the same time, the upward movement of the second locking member can drive the pressing assembly to swing toward the workpiece mounting part 6 so that the pressing assembly is pressed against the support surface of the workpiece mounting part 6.

[0042] As the guide rod 41 moves downward along the height direction, the elastic element 42 recovers its deformation under the drive of the guide rod 41. The second locking element moves downward and away from the transverse rotating plate 31. Because the elastic element 42 has an elastic pushing force to recover its deformation, it can apply a downward elastic pushing force to the top surface of the transverse rotating plate 31 from above. In this way, the vertical snap plate 32 connected to the transverse rotating plate 31 swings away from the workpiece mounting part 6, thereby causing the snap part 33 to disengage from the side of the workpiece mounting part 6, and the pressing assembly to disengage from the support surface of the workpiece mounting part 6. The entire anti-stepping device can be directly removed.

[0043] This application utilizes the up-and-down movement of the guide rod 41 and the elastic force of the elastic element 42 to enable the snap-fit ​​element 3 and the clamping assembly to engage or disengage from the workpiece mounting part 6, thereby facilitating the assembly and disassembly of the entire anti-trampling device from the workpiece mounting part 6. The assembly and disassembly are simple, and the connection, fixation, loosening, and removal can be completed by moving a single guide rod 41.

[0044] It should be noted that the cooperation structure between the guide rod 41 and the first locking member 43 in this application is a bolt structure. The first locking member 43 can be a nut for locking the guide rod 41, while the guide rod 41 is equivalent to the screw structure of a bolt. The up and down movement of the guide rod 41 can be adjusted by turning the nut clockwise or counterclockwise.

[0045] In some embodiments, the clamping assembly includes two clamping blocks 45. Since the support surface of the workpiece mounting part 6 is an arc-shaped structure, the contact positions between the two clamping blocks 45 and the surface of the workpiece mounting part 6 are at different heights on the horizontal plane, so as to achieve clamping at different positions on a section of arc-shaped surface and improve the stability of the entire pedal 1.

[0046] Since the supporting surface of the workpiece mounting component 6 is an inclined surface with a certain curvature, in order to ensure that the clamping block 45 applies a better clamping force to the workpiece mounting component 6, a guide inclined surface is formed at the end of the clamping block 45 that abuts against the workpiece mounting component 6. When the guide rod 41 moves up or down, it can drive the clamping block 45 to swing toward or away from the workpiece mounting component 6. When the clamping block 45 abuts against the workpiece mounting component 6, the setting of the guide inclined surface can prevent the clamping block 45 from causing certain damage to the workpiece mounting component 6 during the clamping process.

[0047] In some embodiments, the second locking member includes a bushing 441 and a mounting portion 442 extending outward from the bushing 441. The bushing 441 is fixedly sleeved on the outer periphery of the guide rod 41. To avoid interference between the mounting portion 442 and the vertical plate 11 during the up-and-down movement of the guide rod 41, a through-hole extending in the height direction is provided on the vertical plate 11. The end of the mounting portion 442 opposite to the bushing 441 is movably inserted into the through-hole. When the bushing 441 moves up and down with the guide rod 41, the mounting portion 442 can move in the height direction along with the bushing 441 within the through-hole.

[0048] Among them, such as Figure 3 As shown, two clamping blocks 45 are arranged corresponding to two vertical plates 11. Each clamping block 45 includes a rotating part 451 and a clamping part 452 connected by an arc-shaped transition. The rotating part 451 is hinged to both sides of the mounting part 442. The clamping part 452 extends from the bottom surface of the vertical plate 11 and is inclined towards the support surface of the workpiece mounting part 6. Furthermore, the clamping part 452 in the clamping block 45 on the right side includes a horizontal connecting part and a vertical connecting part. The horizontal connecting part extends in the left-right direction and has a certain inclination angle towards the workpiece mounting part 6. The vertical connecting part extends in the height direction and is located on the outside of the vertical plate 11.

[0049] It should be noted that since the clamping block 45 has a hollow structure in the middle and is hinged to both sides of the mounting part 442, when the mounting part 442 moves upward, it drives the clamping part 452 to move upward and abut against the bottom surface of the vertical plate 11. Since the rotating part 451 is hinged to the mounting part 442, when the mounting part 442 continues to move upward, the vertical plate 11 applies a downward pushing force to the clamping part 452, thereby driving the end of the clamping part 452 away from the rotating part 451 to swing downward to press against the surface of the workpiece mounting part 6, further improving the stability of the entire pedal 1.

[0050] In some embodiments, the pedal 1 is further provided with a side plate 12 extending along the length direction, and a guide hole 23 extending along the length direction is provided on the side plate 12. The support positioning member 2 and the guide hole 23 are respectively located at both ends of the pedal 1 along the width direction. The anti-pedaling device also includes a guide shaft 22, one end of which is connected to the support positioning member 2, and the other end is slidably inserted into the guide hole 23.

[0051] The guide hole 23 is an elongated hole extending along its length. The top end of the support positioning member 2 is slidably connected to the bottom surface of the pedal 1 and can slide along the length of the pedal 1. For different types of workpieces 5, the support positioning member 2 can be moved in the left and right directions by sliding the guide shaft 22 in the guide hole 23, so that the support positioning member 2 can be positioned at different positions on the workpiece 5.

[0052] In some embodiments, the support positioning member 2 is a block structure with a notch 21 at its end that engages with the workpiece 5. When the anti-trampling device is placed on the support surface of the workpiece mounting member 6, initial positioning is achieved by engaging the notch 21 of the support positioning member 2 with the end or side wall of the workpiece 5. The position where the notch 21 engages with the workpiece 5 can be determined according to actual needs. After the initial positioning is completed, the entire foot pedal 1 is positioned above the workpiece 5 for convenient operation.

[0053] It should be noted that the supporting positioning component 2 is a block structure with a certain height. After positioning is completed, this ensures that a certain installation space is maintained between the bottom surface of the pedal 1 and the upper surface of the workpiece 5, preventing interference between the components on the surface of the pedal 1 and the workpiece 5. Additionally, as... Figure 1 As shown, the support positioning component 2 is positioned near the right end of the pedal 1 and maintains a certain distance from the locking component 3 on the left end. This ensures that the cooperation between the support positioning component 2 and the locking component 3 provides more stable support for the pedal 1.
