Description

Technical Field

[0001] The present invention belongs to the technical field of slope construction, and particularly relates to a slope operation platform for scaffold-free construction. Background Art

[0002] In water conservancy projects, especially during the construction of river channels and dams, most of the main construction locations are on inclined slopes. During slope operation, a temporary slope construction platform is generally used to carry construction workers, so that the construction workers are on a relatively stable plane during slope operation to ensure construction safety and construction accuracy. Such a slope construction platform is generally a temporarily erected scaffold or a manually suspended operation platform. The method of temporarily erecting a scaffold requires a large amount of materials and time, and has a large construction difficulty and low construction efficiency; the method of a manually suspended operation platform is affected by the weather and has a high risk, and also has certain limitations.

[0003] Therefore, in existing water conservancy projects, there is also another way to provide platform support for slope operation. For example, a simple device for a mobile high-slope construction platform disclosed in a Chinese utility model patent with the authorization publication number CN209482322U includes a four-wheel base, a lifting mechanism, and a fence working platform. The fence working platform is connected to the four-wheel base through an angle control rod to facilitate adjusting the angle of the fence working platform; the lifting mechanism is fixed at the top of the slope and pulls the four-wheel base to move up and down along the slope through a traction rope, and then drives the fence working platform to move up and down along the slope, so that construction workers can stand on the fence working platform to perform slope operation, ensuring construction safety and improving construction efficiency.

[0004] However, during the actual construction process, due to construction technology and precision problems, it cannot be guaranteed that the slopes of the slopes are completely consistent, and there will be ups and downs on the construction surface of the slope, resulting in jitter and inclination of the fence working platform when moving up and down along the slope, bringing great potential safety hazards to the construction workers on the construction platform, and at the same time affecting construction precision. Summary of the Invention

[0005] Based on this, the present application provides a slope operation platform for scaffold-free construction to solve the problem that it is difficult to ensure the safety of construction workers and construction precision of the slope operation platform in the prior art.

[0006] The above object is achieved by the following technical solutions: A slope operation platform for shelf-free construction, including a lifting mechanism, a moving support, and a working platform. The working platform is arranged on the moving support. The lifting mechanism can pull the moving support to move up and down along the slope, and then drive the working platform to move up and down. It also includes a traction mechanism. The traction mechanism is fixedly connected to the moving support. The lifting mechanism is connected to the traction mechanism to pull the moving support to move up and down along the slope. The traction mechanism includes a movable pulley, a balance rope, a first rotating frame, a first winding disc, a first torsion spring, a second rotating frame, a second winding disc, and a second torsion spring. The lifting mechanism is connected to the axis of the movable pulley. The middle of the balance rope bypasses the movable pulley. The two ends of the balance rope are respectively connected to the first winding disc and the second winding disc. The first winding disc and the second winding disc are rotationally assembled on the moving support. The first rotating frame and the second rotating frame are hinged on the moving support. The first rotating frame can lock the first winding disc, and the second rotating frame can lock the second winding disc. Define the pulling force direction provided by the lifting mechanism as the standard direction. When the angle by which the front end of the moving support deviates downward relative to the standard direction exceeds the set angle, the first rotating frame releases the lock on the first winding disc, and the first torsion spring can drive the first winding disc to rotate to wind the balance rope, thereby pulling the moving support upward. When the angle by which the front end of the moving support deviates upward relative to the standard direction exceeds the set angle, the second rotating frame releases the lock on the second winding disc, and the second torsion spring can drive the second winding disc to rotate to wind the balance rope, thereby pulling the moving support upward.

[0007] Further, a first one-way ratchet is provided on the end face of the first winding disc, and a first locking protrusion is provided on the first rotating frame. The first rotating frame is in locking cooperation with the first one-way ratchet through the first locking protrusion to prevent the first torsion spring from driving the first winding disc to rotate. When the angle by which the front end of the moving support deviates downward relative to the standard direction exceeds the set angle, the first locking protrusion is disengaged from the first one-way ratchet, and the first torsion spring drives the first winding disc to rotate to wind the balance rope.

[0008] Further, the first rotating frame is hinged to the moving support. The hinge point of the first rotating frame is in front of the first winding disc, and the first locking protrusion is below the first winding disc. One end of the balance rope connected to the first winding disc passes through the first rotating frame. When the front end of the moving support deviates downward relative to the standard direction, the first one-way ratchet moves synchronously away from the first locking protrusion.

[0009] Further, second one-way ratchets are provided on the end face of the second winding disc, second locking protrusions are provided on the second rotating frame, and the second rotating frame is in locking cooperation with the second one-way ratchets through the second locking protrusions to prevent the second torsion spring from driving the second winding disc to rotate; when the angle by which the front end of the moving bracket deviates upward relative to the standard direction exceeds a set angle, the second locking protrusion is disengaged from the second one-way ratchet, and the second torsion spring drives the second winding disc to rotate to wind up the balance rope.

[0010] Further, the second rotating frame is hinged to the moving bracket, the hinge point of the second rotating frame is located in front of the second winding disc, the second locking protrusion is located above the second winding disc, and one end of the balance rope connected to the second winding disc passes through the second rotating frame. When the front end of the moving bracket deviates upward relative to the standard direction, the second one-way ratchet synchronously moves away from the second locking protrusion.

[0011] Further, the moving bracket includes a base and traveling wheels. There are at least three traveling wheels, and the traveling wheels are rotatably installed at the bottom of the base. The first winding disc and the second winding disc are rotatably assembled on the base.

[0012] Further, the moving bracket further includes an angle adjusting rod. The lower end of the angle adjusting rod is hinged to the base, the upper end of the angle adjusting rod is hinged to the working platform, the rear end of the working platform is hinged to the base, and the angle adjusting rod can be telescopically adjusted to change the inclination angle of the working platform.

[0013] Further, a first rotating shaft is provided on the moving bracket. The first winding disc is rotatably assembled on the first rotating shaft. A cavity is provided inside the first winding disc. An annular first buffer cavity is formed between the inner cavity wall of the first winding disc and the outer peripheral surface of the first rotating shaft. The first buffer cavity is filled with a damping medium to slow down the rotation speed of the first winding disc.

[0014] Further, a second rotating shaft is provided on the moving bracket. The second winding disc is rotatably assembled on the second rotating shaft. A cavity is provided inside the second winding disc. An annular second buffer cavity is formed between the inner cavity wall of the second winding disc and the outer peripheral surface of the second rotating shaft. The second buffer cavity is filled with a damping medium to slow down the rotation speed of the second winding disc.

[0015] Further, the working platform includes a bottom plate and a guardrail. The guardrail is arranged around the circumference of the bottom plate.

[0016] The beneficial effects of the slope operation platform with no rack construction provided by the present invention are as follows: A traction mechanism is provided on the moving support. The lifting mechanism drives the moving support to move up and down along the slope by pulling the traction mechanism. The traction mechanism can perform corresponding feedback actions according to the attitude change of the moving support to avoid excessive inclination of the moving support and affect the levelness of the working platform, ensuring the safety of the operators and the construction accuracy. Specifically, during the process of the moving support moving down along the slope, if it passes through a slope area with a too large slope deviation, causing the deviation angle of the front end of the moving support relative to the pulling direction of the lifting mechanism to exceed the set angle, the traction mechanism drives the moving support to rise, so that the moving support automatically gets out of this area. At this time, even if the lifting mechanism continues to lower, under the action of the traction mechanism, the moving support cannot pass through this slope area with a too large slope deviation, thereby reminding the operators to make corresponding adjustments to avoid the unstable factors caused by the sudden change of the inclination angle of the moving support, thus effectively improving the safety of slope operation and the construction accuracy.

[0032] The following will explain the slope operation platform for scaffolding-free construction provided by the present invention in conjunction with the accompanying drawings of the specification and specific embodiments.

[0033] Embodiment 1 of the slope operation platform for scaffolding-free construction of the present invention: Refer to Figures 1 to 11 As shown, the slope operation platform for scaffolding-free construction mainly includes a lifting mechanism (not shown in the figure), a traction mechanism, a moving support and a working platform. The working platform is arranged on the moving support, and the lifting mechanism is fixed at the top of the slope. The lifting mechanism includes a winch and a traction rope. One end of the traction rope is connected to the winch, and the other end of the traction rope is connected to the rear end of the moving support through the traction mechanism. The winch can pull the traction mechanism to move by winding and unwinding the traction rope, so as to drive the moving support to move up and down along the slope, and further drive the working platform on the moving support to move up and down along the slope.

[0034] Specifically, the moving support mainly includes a base 200, traveling wheels 220 and angle adjusting rods 210. In this embodiment, there are four traveling wheels 220 on the moving support, and the four traveling wheels 220 are evenly and symmetrically rotatably installed at the bottom of the base 200 to ensure the movement of the base 200. The rear end of the working platform is hinged to the rear end of the base 200, so that the front end of the working platform can swing on the base 200 to facilitate the adjustment of the inclination angle of the working platform.

[0035] Among them, the front end of the working platform is connected to the front end of the base 200 through the angle adjusting rod 210. Specifically, the upper end of the angle adjusting rod 210 is hinged to the front end of the working platform, and the lower end of the angle adjusting rod 210 is hinged to the front end of the base 200. In this embodiment, the angle adjusting rod 210 is a hydraulic rod that can be telescopically adjusted. The user can control the telescopic movement of the angle adjusting rod 210 to change the inclination angle of the working platform, so that when the moving bracket moves up and down along the slope, the working platform can be in a horizontal state, effectively ensuring the safety of the operators and facilitating construction. The working platform includes a bottom plate 300 and a guardrail 310. The guardrail 310 is arranged around the circumference of the bottom plate 300. When performing slope operations, the operators stand on the bottom plate 300, and the guardrail 310 around the bottom plate 300 can effectively protect the operators to prevent them from falling off the working platform.

[0036] In this embodiment, the traction mechanism mainly includes a movable pulley 100, a balance rope 101, a first rotating frame 110, a first winding disc 111, a first torsion spring 115, a second rotating frame 120, a second winding disc 121 and a second torsion spring 125. A horizontally extending first rotating shaft 112 and a second rotating shaft 122 are fixedly arranged on the base 200 of the moving bracket. The first winding disc 111 is rotatably assembled on the first rotating shaft 112. The first winding disc 111 is connected to the base 200 through the first torsion spring 115, and the first torsion spring 115 can drive the first winding disc 111 to rotate. The second winding disc 121 is rotatably assembled on the second rotating shaft 122. The second winding disc 121 is connected to the base 200 through the second torsion spring 125, and the second torsion spring 125 can drive the second winding disc 121 to rotate.

[0037] One end of the balance rope 101 is connected to the first winding disc 111, and the other end passes around the movable pulley 100 and is connected to the second winding disc 121. The winch is connected to the axis of the movable pulley 100 through a traction rope. The traction rope can pull the movable pulley 100 to move up and down along the slope, thereby driving the moving bracket to move up and down along the slope.

[0038] The first rotating frame 110 is hinged to the base 200 of the moving bracket. The hinge point of the first rotating frame 110 is located on the front side of the first rotating shaft 112. A first locking protrusion 113 is arranged on the first rotating frame 110. Correspondingly, a first one-way ratchet 114 is arranged on the first winding disc 111. The first locking protrusion 113 is located below the first one-way ratchet 114. The first locking protrusion 113 can be locked and matched with the first one-way ratchet 114, thereby realizing the locking of the first rotating frame 110 to the first winding disc 111 and preventing the first torsion spring 115 from driving the first winding disc 111 to rotate.

[0039] Similarly, the second rotating frame 120 is hinged on the base 200 of the mobile bracket, and the hinge point of the second rotating frame 120 is located at the front side of the second rotating shaft 122. The second rotating frame 120 is provided with a second locking protrusion 123. Correspondingly, the second winding disc 121 is provided with a second one-way ratchet 124, and the second locking protrusion 123 is located below the second one-way ratchet 124. The second locking protrusion 123 can be locked and matched with the second one-way ratchet 124, thereby realizing the locking of the second rotating frame 120 on the second winding disc 121, and preventing the first torsion spring 115 from driving the first winding disc 111 to rotate.

[0040] The direction of the pulling force provided by the traction rope is defined as the standard direction, and the slope surface in which the slope is always in an ideal state of constant slope is defined as the standard slope surface. In the process of the mobile bracket moving downward along the slope, if it passes through a slope area with a large slope deviation, so that the angle of the front end of the mobile bracket deviates downward relative to the standard direction exceeds the set angle, the hinge point of the first rotating frame 110 moves downward, driving the first locking protrusion 113 to move downward and disengage from the first one-way ratchet 114, releasing the lock on the first winding disk 111, and releasing the first torsion spring 115 in a twisted state, driving the first winding disk 111 to rotate, winding the balance rope 101, and then pulling the mobile bracket to move up along the slope.

[0041] If the angle at which the front end of the movable bracket deviates upward relative to the standard direction exceeds a set angle, the hinge point of the second rotating frame 120 moves downward, driving the second locking protrusion 123 to move downward and disengage from the second one-way ratchet 124, thereby releasing the lock on the second winding drum 121, and releasing the second torsion spring 125 in a twisted state, driving the second winding drum 121 to rotate, thereby winding up the balance rope 101, and thereby pulling the movable bracket up along the slope.

[0042] In general, when the mobile support is lowered along the slope, when the mobile support moves to a slope area with a large slope deviation, that is, the angle of deviation of the mobile support relative to the standard direction exceeds the set angle, the first rotating frame 110 or the second rotating frame 120 can correspondingly release the lock of the first winding disk 111 or the second winding disk 121, and the first winding disk 111 or the second winding disk 121 pulls the mobile support back by winding the balance rope 101, so that the mobile support is separated from the slope area with a large slope deviation, and the mobile support is prevented from continuing to move downward, ensuring the construction safety of the operators. At the same time, the operators are reminded to make corresponding adjustments to the device to avoid the unstable factors caused by the sudden change of the tilt angle of the mobile support, which effectively improves the safety of slope operations and is conducive to ensuring construction accuracy.

[0043] Further, a cavity is provided inside the first winding reel 111, such that an annular first buffer cavity 116 is formed between the inner cavity wall of the first winding reel 111 and the outer peripheral surface of the first rotating shaft 112. The first buffer cavity 116 is filled with a damping medium to slow down the rotation speed of the first winding reel 111. Similarly, a cavity is also provided inside the second winding reel 121, such that an annular second buffer cavity is formed between the inner cavity wall of the second winding reel 121 and the outer peripheral surface of the second rotating shaft 122. The second buffer cavity is filled with a damping medium to slow down the rotation speed of the second winding reel 121.

[0044] In this embodiment, the damping media in the first buffer cavity 116 and the second buffer cavity can both adopt high-viscosity silicone oil. As the damping medium, the high-viscosity silicone oil can provide sufficient resistance to counteract the torsional forces of the first torsion spring 115 and the second torsion spring 125, ensuring the buffering effect on the first winding reel 111 and the second winding reel 121, avoiding the excessive winding speed of the first winding reel 111 and the second winding reel 121 from causing severe shaking of the working platform, effectively ensuring the safety of the operators, and at the same time avoiding the shaking from affecting the construction accuracy.

[0045] Further, an adjusting push plate 130 and a cooperating push plate 140 are provided inside the first buffer cavity 116. The adjusting push plate 130 can adjust and move inside the first buffer cavity 116 to change the volume of the first buffer cavity 116, thereby changing the pressure inside the first buffer cavity 116, and thus changing the resistance exerted by the damping medium inside the first buffer cavity 116 on the first winding reel 111. The cooperating push plate 140 is elastically pushed and cooperated with the inner cavity wall of the first buffer cavity 116 through a cooperating spring 141, and the cooperating spring 141 pushes the cooperating push plate 140 to apply pressure to the first buffer cavity 116. When the adjusting push plate 130 moves to change the pressure inside the first buffer cavity 116, the cooperating push plate 140 correspondingly guides and moves inside the first buffer cavity 116 to compress the cooperating spring 141 to release some space, thereby effectively controlling the pressure of the first buffer cavity 116 and avoiding structural jamming or failure due to excessive pressure. The structure and function of the second buffer cavity are basically the same as those of the first buffer cavity 116, and no redundant description will be given here.

[0046] It should be noted that, in this embodiment, the base 200 of the moving support includes two moving rods. A traveling wheel 220 is rotatably installed at each of the front and rear ends of the moving rods, and the two moving rods support the working platform from the left and right sides respectively. Correspondingly, two angle adjusting rods 210 are also provided, and two sets of traction mechanisms are also provided, which are respectively assembled and connected corresponding to the two moving rods.

[0047] The following will refer to Figures 1 - 11 shown and further illustrate the slope operation platform for scaffold-free construction of the present application in combination with the specific use process.

[0048] (i) In the initial state, the winch is first fixed to the top of the slope, and the winch is connected to the axis of the movable pulley 100 of the traction mechanism through a traction rope to achieve traction of the mobile bracket. Under the pull of the traction rope, the working platform is slowly lowered from the top of the slope until the working platform is completely on the slope.

[0049] (ii) The device as a whole is adjusted, and the first torsion spring 115 and the second torsion spring 125 are twisted and stored so that the torsion restoring force provided by the first torsion spring 115 and the second torsion spring 125 is greater than the sum of the overall weight of the device and the weight of the operator, so that the first torsion spring 115 and the second torsion spring 125 can respectively drive the first winding drum 111 and the second winding drum 121 to automatically wind up the balance rope 101.

[0050] At the same time, when the mobile bracket is completely on the slope, the base 200 is kept parallel to the slope, the first rotating frame 110 is locked to the first winding disk 111, and the second rotating frame 120 is locked to the second winding disk 121. Then the angle adjustment rod 210 is controlled to be telescopically adjusted to make the working platform in a horizontal state, and the operator enters the working platform.

[0051] (3) Control the winch to slowly lower the traction rope at a uniform speed, so that the mobile support moves slowly downward along the slope, so that the workers on the work platform can perform slope operations.

[0052] When the mobile support moves downward along the slope, when the mobile support passes through a slope area with a large slope deviation, the front end of the mobile support will be excessively tilted up or sunk, that is, the angle of deviation of the front end of the mobile support relative to the pulling direction of the traction rope exceeds the set angle. At this time, the first rotating frame 110 releases the lock on the first winding drum 111 or the second winding drum 121 releases the lock on the second winding drum 121, and the first winding drum 111 or the second winding drum 121 winds up the balance rope 101, driving the mobile support to move upward, so that the mobile support automatically leaves the slope area with a large slope deviation.

[0053] Under the automatic recovery action of the traction mechanism, even if the lifting mechanism continues to be lowered, the mobile bracket will not be able to pass through the slope area with excessive slope deviation, avoiding sudden changes in the inclination angle of the mobile bracket that may cause sudden shaking and tilting of the working platform, effectively ensuring the safety of the operators and reminding them to make corresponding adjustments to ensure construction accuracy.

[0054] Of course, the slope working platform for construction without a rack of the present invention is not limited to the above-mentioned embodiments. The following provides several other embodiments of the slope working platform for construction without a rack of the above-mentioned embodiments.

[0055] In other embodiments of the slope operation platform for scaffolding-free construction of the present invention, different from the above embodiments: the number of traveling wheels in the mobile support may not be set to four, and may also be set to three or more than four. Taking the case of setting three traveling wheels as an example, the base is set as a triangular frame, the angle adjustment rod is hinged at the front end of the base, and the traction mechanism is connected to the rear end of the base, as long as the stability of the working platform can be ensured.

[0056] In other embodiments of the slope operation platform for scaffolding-free construction of the present invention, different from the above embodiments: the first rotating frame and the second rotating frame may adopt other types of locking and matching structures to lock the first winding disc and the second winding disc. For example, an automatic spring buckle or an extrusion inclined plane is used to achieve the locking and matching, as long as the locking of the first winding disc or the second winding disc can be released when the deviation angle of the mobile support is greater than the set value.

[0057] In other embodiments of the slope operation platform for scaffolding-free construction of the present invention, different from the above embodiments: the first winding disc and the first rotating shaft, and the second winding disc and the second rotating shaft may not adopt a buffer cavity filled with a damping medium to achieve buffering, and may also adopt a friction mating surface to provide frictional resistance to slow down the relative rotation speed between the two.

[0058] In other embodiments of the slope operation platform for scaffolding-free construction of the present invention, different from the above embodiments: the damping medium in the first buffer cavity and the second buffer cavity may not adopt high-viscosity silicone oil, and may also adopt other types of high-viscosity fluids, such as liquid resin, quicksand, etc.

[0059] The above embodiments only represent several specific implementation manners of the present invention. The description is relatively specific and detailed. To make the content brief, not all possible combinations of the various technical features in the above embodiments are described. However, it should not be understood as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, as long as the combination of these technical features does not conflict, several deformations and improvements can still be made, and these should all be considered within the scope described in this specification. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
