Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for runoff plots, specifically relating to an auxiliary working platform for slope maintenance in runoff plots. Background Technology

[0002] A runoff plot is a general term for facilities used to observe the patterns of slope water erosion and its influencing factors. To ensure the accuracy of runoff plot test results, it is necessary to regularly clear weeds from the slopes of bare runoff plots and regularly maintain the sensors buried in the runoff plots. Initially, workers would often squat directly on the slopes of the runoff plots to handle weeds and maintain sensors. This process would trample on the slopes and damage their structure, necessitating post-work slope restoration. However, subsequent tests showed that the restored slopes still differed from the original slopes, affecting the test results. Therefore, to avoid damaging the slopes during weeding and sensor maintenance, workers began to build an auxiliary working platform in the work area. The existing auxiliary working platform consists of a working board and two fixed legs. During construction, the two fixed legs are first fixed to both sides of the runoff plot, and then the working platform is erected on the fixed legs. Workers use the fixed legs to climb onto the working platform and squat on it to complete the weed clearing and sensor maintenance work. While this auxiliary working platform effectively protects the runoff plot slopes, it still has two drawbacks in its use:

[0003] First, the safety is poor. There are no protective devices for workers on the work board, especially in the center of the work board, which is far from the fixed support. The work board is not level, and the board shakes a lot when workers move on it. Workers are prone to leaning backward when squatting or standing up. If they are not careful, they will fall onto the work board, which will cause a safety accident.

[0004] Secondly, the mobility is poor. Since the growth position of weeds on the slope is not fixed, it is necessary to change the location of the auxiliary work platform many times in order to complete the weed clearing work. This requires repeated construction of the auxiliary work platform, which is very time-consuming and labor-intensive, and greatly reduces the work efficiency of slope maintenance in the runoff area.

[0005] Therefore, in order to overcome the above two shortcomings, it is very much in line with practical needs to develop an auxiliary work platform that is highly safe and easy to move. Utility Model Content

[0006] In order to solve the problems of poor safety and poor mobility of the auxiliary working platforms used in existing runoff plots for slope maintenance, this utility model provides an auxiliary working platform for slope maintenance in runoff plots.

The push rod motor is located between the connecting plate and the bottom fixing plate, and the length of the push rod motor extends in the same direction as the width of the working plate. The tail end of the push rod motor is located in the mounting base and is hinged to the mounting base. The mounting base is located near the second hinge ear and is fixedly connected to the top of the bottom fixing plate. The piston rod end of the push rod motor is hinged to the hinge rod through the hinge seat.

[0012] Furthermore, at least one support column is provided on the bottom of the connecting plate at the end away from the first hinge ear. The top of the support column is fixedly connected to the bottom of the connecting plate, and a rubber sleeve is provided on the bottom of the support column.

[0013] Furthermore, the drive unit includes a turntable and a tracked transport vehicle. The turntable is integrated on the tracked transport vehicle, and the bottom fixing plate is set on the turntable and detachably connected to the turntable.

[0014] Furthermore, the auxiliary work frame also includes two stretching units, each of which is correspondingly set on the top of a work plate angle adjustment unit, and the fixed end of each stretching unit is fixedly connected to the work plate angle adjustment unit, and the stretching end of each stretching unit extends to the work plate and is fixedly connected to the work plate.

[0015] Furthermore, the tensioning unit includes a U-shaped frame and two cable assemblies. The U-shaped frame is inverted on top of the connecting plate and fixedly connected to the connecting plate. Each cable assembly is disposed between a vertical frame in the U-shaped frame and the working plate.

[0017] The beneficial effects of this application compared to the prior art are:

[0018] This application provides an auxiliary working platform for slope maintenance in runoff areas. Compared with traditional auxiliary working platforms, it adds a rear guardrail and a bottom reinforcement block to its working platform. The rear guardrail is used to protect construction personnel and prevent them from falling off the working platform due to backward inertia. At the same time, a reinforcement block is set at the bottom center of the working platform to increase the support strength in the middle of the working platform and reduce the shaking amplitude of the working platform, thereby improving the safety of the workers.

[0019] This application provides an auxiliary working platform for slope maintenance in runoff areas. Compared with traditional auxiliary working platforms, the support structure is optimized. The traditional fixed support is optimized into a mobile support constructed by a working angle adjustment unit and a drive unit. The working angle adjustment unit is used to adjust the working angle of the working plate so that the working plate is always horizontal with the ground, providing a good working area for the staff. The drive unit can drive the working angle adjustment unit and the working plate as a whole to move along the extension direction of the slope, so as to meet the needs of clearing weeds in multiple places on the slope and inspecting and maintaining multiple sensors on the slope. This improves the flexibility of the auxiliary working platform and makes it easier to change the work position of the auxiliary working platform.

[0020] This application provides an auxiliary working platform for slope maintenance in runoff areas. To further improve the working stability of the working plate, a tensioning unit is added. The tensioning unit pulls the working plate with cables, which improves the working stability of the working plate and prevents the plate from bending and deforming significantly when workers step on it. It also helps to reduce the shaking of the plate when workers move on it. Attached Figure Description

[0033] Combination Figures 1 to 11 This embodiment describes an auxiliary working platform for slope maintenance in a runoff area. The auxiliary working platform includes a working plate 1, with a support and movement component located below each end of the working plate 1. Each support and movement component is detachably connected to the working plate 1 by bolts.

[0034] The supporting moving assembly includes a work plate angle adjustment unit 2 and a drive unit 3. The work plate angle adjustment unit 2 is located on top of the drive unit 3 and is detachably connected to the drive unit 3. The work plate 1 is located above the work plate angle adjustment unit 2, and one end of the work plate 1 is detachably connected to the work plate angle adjustment unit 2 by bolts.

[0035] In this embodiment, the working board 1 is the main support platform for workers. Workers squat on the working board 1 to clear weeds on the slope and maintain the sensors on the slope. The working board angle adjustment unit 2 is used to adjust the working angle of the working board 1 so that the working board 1 is always parallel to the ground to ensure the stability of the workers during construction. The drive unit 3 is used to move the auxiliary working platform to facilitate the adjustment of the working position of the auxiliary working platform.

[0036] Combination Figures 1 to 11 This embodiment differs from Specific Embodiment 1 in that a guardrail 4 is provided on the outer side of the top of the work plate 1, and the guardrail 4 is detachably connected to the work plate 1. Other components and connection methods are the same as in Specific Embodiment 1.

[0037] Combination Figures 1 to 11 This embodiment differs from Specific Embodiment Two in that a reinforcing block 5 is provided at the bottom center of the working plate 1, and the reinforcing block 5 is integrally formed with the working plate 1. Other components and connection methods are the same as in Specific Embodiment Two.

[0038] In conjunction with the descriptions of specific implementation methods two and three, adding a guardrail 4 to the rear side of the work board 1 can protect construction workers and prevent them from falling off the work board due to the backward inertia when squatting and standing up. A reinforcing block 5 is set at the bottom center of the work board 1 to increase the support strength of the middle part of the work board 1 and reduce the shaking amplitude of the work board 1, thereby improving the safety of the workers.

[0039] Combination Figures 1 to 11 This embodiment differs from specific embodiment three in that the working plate angle adjustment unit 2 includes a connecting plate 21, a hinge rod 24, a push rod motor 25, a mounting base 26, and a bottom fixing plate 28. The connecting plate 21 is located below one end of the working plate 1 and is detachably connected to the working plate 1 by bolts. The bottom fixing plate 28 is located below the connecting plate 21 and is located on top of the drive unit 3 and is detachably connected to the drive unit 3. The bottom of one end of the connecting plate 21 has two first hinge ears 22, and the top of the bottom fixing plate 28 has two second hinge ears 23. Each second hinge ear 23 is correspondingly matched with one first hinge ear 22. Each hinge ear 22 is hinged to its corresponding hinge ear 23 via a pin. A hinge rod 24 is mounted on the bottom of the other end of the connecting plate 21 via two fixing blocks, and the axis of the hinge rod 24 extends in the same direction as the length of the working plate 1. A push rod motor 25 is positioned between the connecting plate 21 and the bottom fixing plate 28, and the length of the push rod motor 25 extends in the same direction as the width of the working plate 1. The tail end of the push rod motor 25 is mounted in the mounting base 26 and hinged to it. The mounting base 26 is positioned near the hinge ear 23 and fixedly connected to the top of the bottom fixing plate 28. The piston rod end of the push rod motor 25 is hinged to the hinge rod 24 via a hinge seat. Other components and connections are the same as in specific embodiment three.

[0040] In this embodiment, the push rod motor 25 serves as the power component for adjusting the swing of the connecting plate 21 relative to the bottom fixed plate 28. With the extension action of the push rod motor 25, the connecting plate 21 is pushed to swing upward, so that the end of the connecting plate 21 is set away from the bottom fixed plate 28, thereby driving the working plate 1 on the connecting plate 21 to swing synchronously, and adjusting the working angle of the working plate 1.

[0041] Combination Figures 1 to 11 This embodiment differs from Specific Embodiment Four in that at least one support column 27 is provided on the bottom of the connecting plate 21 at the end away from the first hinge ear 22. The top of the support column 27 is fixedly connected to the bottom of the connecting plate 21, and a rubber sleeve is fitted on the bottom end of the support column 27. Other components and connection methods are the same as in Specific Embodiment Four.

[0042] In this embodiment, the support column 27 is used as a support structure when the connecting plate 21 and the bottom fixing plate 28 are in a parallel state. The bottom end of the support column 27 is fitted with a rubber sleeve to reduce the impact force between the support column 27 and the bottom fixing plate 28 and to prevent rigid contact between the support column 27 and the bottom fixing plate 28 when the support column 27 swings with the connecting plate 21 toward the bottom fixing plate 28.

[0043] Combination Figures 1 to 11 This embodiment differs from Specific Embodiment Five in that the drive unit 3 includes a rotating platform 38 and a tracked transport vehicle. The rotating platform 38 is integrated onto the tracked transport vehicle, and the bottom fixing plate 28 is mounted on the rotating platform 38 and detachably connected to it. Other components and connection methods are the same as in Specific Embodiment Five.

[0044] In this embodiment, the drive unit 3 is a drive component that controls the movement of the auxiliary work platform. The tracked transport vehicle specifically includes a housing 31, a battery 310, two drive wheels 32, two driven wheels 33, two tracks 34, and two power mechanisms. The housing 31 is divided into a front drive area, a middle rotation area, and a rear power area by a partition. The front drive area is further divided into two drive chambers by a partition, each containing a power mechanism. Each power mechanism includes a driven gear 35, a drive gear 36, and a drive motor 37. The drive motor 37 is a bidirectional motor, mounted on the bottom of its respective drive chamber via a motor mounting bracket, with the power output shaft of each drive motor 37 facing the housing. A drive gear 36 is mounted on the power output shaft of the drive motor 37 and rotates synchronously with it. Two drive wheels 32 are positioned opposite each other on the front end of the housing 31, with the axle of each drive wheel 32 passing through the housing 31 and extending into the corresponding drive chamber. The axle of each drive wheel 32 is rotatably connected to the housing 31 via a bearing. A driven gear 35 is mounted on the axle of the drive gear 36 and rotates synchronously with it. The driven gear 35 also meshes with the drive gear 36. Two driven wheels 33 are positioned opposite each other on the rear end of the housing 31, with the axle of each driven wheel 33 inserted into the side wall of the rear end of the housing 31 and rotatably connected to it via a bearing. Two tracks 34 are respectively arranged on both sides of the housing 31, and each track is respectively fitted onto a set of drive wheels 32 and driven wheels 33 located on the same side of the housing 31. The battery 310 is arranged in the power area at the rear of the housing 1 and is detachably connected to the housing 1 through the battery mounting bracket. At the same time, the power output terminal of the battery 310 is connected to two drive motors 37 through wires and supplies power to the two drive motors 37. As the drive motors 37 rotate, they drive the drive wheels 32 to rotate, which in turn drives the tracks 34 to rotate in a cycle, thereby driving the driven wheels 33 to rotate synchronously. In order to ensure the stability of the tracks 34, multiple tensioning wheels can be added between the drive wheels 32 and the driven wheels 33 to tension the tracks 34. The rotating table 38 is mounted on the housing 31 by the fixing ring 39. The fixing ring 39, located at the bottom of the central rotating area, is detachably connected to the bottom of the housing 31 via bolts. Simultaneously, the fixing ring 39 is detachably connected to the outer shell of the rotating platform 38 via bolts. To improve the working stability of the fixing ring 39, multiple reinforcing ribs are equidistantly arranged circumferentially on the outer surface of the fixing ring 39, and each reinforcing rib is fixedly connected to the fixing ring 39. The power output terminal of the battery 310 is also connected to the power input terminal of the rotating platform 38 via wires to supply power to the rotating platform 38. To improve the operability of the tracked transport vehicle, a PLC controller is also integrated into the tracked transport vehicle. The PLC controller is installed on the side wall of the central rotating area or the rear power area, and is connected to the control terminals of the drive motor 37 and the rotating platform 38 via wires.The PLC controller is a QL-20 industrial programmable controller manufactured by Qinglian brand. It has a built-in remote connection module that allows direct connection to a mobile phone. Commands are sent from the mobile phone to the PLC controller to control the operation of the drive motor 37 and the rotating platform 38. To prevent the internal structure of the tracked transport vehicle from being exposed, a cover plate 312 is installed on the top of the housing 31. The center of the cover plate 312 has a through hole corresponding to the rotating platform 38. Multiple insertion posts are also provided at the bottom of the cover plate 312, each integrally formed with the cover plate 312. Multiple vertically extending fixing sleeves are also provided at the bottom of the front drive area and the middle rotating area, with each fixing sleeve coaxially corresponding to one insertion post. During installation, each insertion post of the cover plate 312 is inserted into a fixing sleeve, with a transition fit to ensure the installation stability of the cover plate 312.

[0045] Combination Figures 1 to 11 This embodiment differs from Specific Embodiment Six in that the auxiliary work frame further includes two stretching units. Each stretching unit is correspondingly disposed on the top of a workplate angle adjustment unit 2, and the fixed end of each stretching unit is fixedly connected to the workplate angle adjustment unit 2 to which it is located. The stretching end of each stretching unit extends onto the workplate 1 and is fixedly connected to the workplate 1. Other components and connection methods are the same as in Specific Embodiment Five.

[0046] Combination Figures 1 to 11 This embodiment differs from specific embodiment seven in that the stretching unit includes a 'U'-shaped frame 6 and two cable assemblies. The 'U'-shaped frame 6 is inverted on top of the connecting plate 21 and fixedly connected to the connecting plate 21. Each cable assembly is disposed between a vertical frame in the 'U'-shaped frame 6 and the working plate 1, and one end of each cable assembly is fixedly connected to a vertical frame in the 'U'-shaped frame 6, and the other end of each cable assembly is fixedly connected to the top of the working plate 1.

[0047] The cable assembly includes at least one cable mechanism, which includes a cable 7, a frame connecting ring 61, and a work plate connecting ring 11. The frame connecting ring 61 is mounted on one of the frame members of the U-shaped frame 6, and the work plate connecting ring 11 is mounted on the top of the work plate 1. The cable 7 is disposed between the frame connecting ring 61 and the work plate connecting ring 11, with one end of the cable 7 detachably connected to the frame connecting ring 61 and the other end of the cable 7 detachably connected to the work plate connecting ring 11. Other components and connection methods are the same as in specific embodiment five.

[0048] In conjunction with the descriptions of specific implementation methods seven and eight, the development concept of the tension unit is based on the cable structure of a cable-stayed bridge. The 'U'-shaped frame 6 located on the connecting plate 21 serves as the vertical bearing support, and the cable 7 serves as the force-bearing cable, forming a self-aligning system with the working plate 1. This allows the working plate 1 to not only overlap with the two connecting plates 21 but also be supported by the cable 7 extended from the 'U'-shaped frame 6, thereby improving the stability of the working plate 1.

[0049] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0050] Working principle

[0051] In operation, this application is first assembled according to the connection relationships described in Specific Embodiments 1 to 8. When idle, the auxiliary work platform is set up in an open area above the runoff area. At this time, in order to facilitate the movement of the auxiliary work platform, the movement direction of the tracked transport vehicle is the same as the length extension direction of the work plate 1. See the attached drawings in the specification for details. Figure 7 The diagram on the right shows the status of the auxiliary working platform. When weed control is needed on the slope of the runoff plot using the auxiliary working platform, the platform is moved directly above the target runoff plot. Then, the rotating platform 38 drives the tracked transport vehicle to rotate 90 degrees, aligning the movement direction of the tracked transport vehicle with the extension direction of the runoff plot. See the attached diagram in the instruction manual for details. Figure 7 The second diagram from the right shows the status of the auxiliary working platform. At this point, the tracked transport vehicle moves the auxiliary working platform along the slope of the runoff plot until it reaches the first area requiring weeding or sensor maintenance. The tracked transport vehicle then stops. Because the runoff plot slope has a certain angle of inclination, the working plate 1 on the auxiliary working platform is currently parallel to the slope, which is not conducive to workers crouching down. Therefore, the push rod motor 25 needs to extend, causing the end of the connecting plate 21 to swing upwards until the connecting plate 21 is in a horizontal working state. See the attached diagram in the instruction manual for details. Figure 7The diagram shows the status of the auxiliary working platform on the far left. At this time, the staff can climb onto the working platform 1 and crouch on it to clear the weeds on the slope or repair the sensors in this area. After the slope maintenance in this area is completed, the staff will control the tracked transport vehicle to drive the auxiliary working platform to continue moving along the slope to the next maintenance area. During this process, the staff can get off the working platform 1 or not, because the outer side of the working platform 1 is equipped with guardrails to effectively prevent the staff from falling. After the auxiliary working platform moves to the next maintenance area, the staff will continue to clear the weeds or maintain the sensors in this area. The above operations are repeated until all the weeds on the slope of the runoff area are cleared. The staff will then get off the auxiliary working platform, and at the same time, the push rod motor 25 will drive the connecting plate 21 back to the initial state. The staff will control the tracked transport vehicle to move to the open area at the top of the runoff area and adjust the movement direction of the tracked transport vehicle through the rotating platform 38 to carry out the maintenance work on the slope of the next runoff area.
