Description

Technical Field

[0001] This application belongs to the field of ground construction technology, and specifically relates to a combined rain shelter mechanism for ground construction. Background Technology

[0002] Ground construction encompasses various engineering types, including earthwork, road construction, and municipal infrastructure. As construction progresses, ground construction projects tend to extend horizontally. During the rainy season, rain shelters are typically installed on-site to protect the construction area from rain damage.

[0003] In the prior art, the common rain-proof mechanism is a rainproof cloth fixed to the outer edge of the construction area by means of support piles. Specifically, the rainproof cloth is rectangular and each of the four corners is connected to a support pile. The support piles are fixedly supported on the ground so that the rainproof cloth can be opened and cover the area directly above the construction area.

[0004] The inventors discovered that as construction progresses, the construction area gradually extends beyond the coverage of the tarpaulin. At this point, whether it is installing a new tarpaulin or removing the original support piles and moving them outward (while replacing or extending the tarpaulin), it will consume a lot of time and ultimately reduce the efficiency of ground construction. Utility Model Content

[0005] This application provides a combined rain shelter mechanism for ground construction, designed to adapt to gradually extending construction areas. The adjustable design enhances the versatility of the mechanism, achieving the technical objective of providing rain shelter for construction areas of different lengths and avoiding any impact on ground construction efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A combined rain shelter mechanism for ground construction is provided, comprising:

[0008] Fixed brackets are used to set up at the starting position of ground construction;

[0009] A movable support frame is used to be positioned at the construction site on the ground and is adapted to slide relative to the construction surface to move toward or away from the fixed support frame, and to shorten or lengthen the distance between the fixed support frame and the movable support frame; the movable support frame has a limiting structure for restricting its movement; and

[0010] A rain shield has one end connected to the movable bracket and the other end fixedly mounted on the fixed bracket via a winding assembly; the winding assembly is used to retract or release the rain shield so that the portion of the rain shield between the fixed bracket and the movable bracket is in a taut state.

[0011] In one possible implementation, the winding assembly has a self-locking function, enabling the taut rainproof strip to restrict the movement of the movable support away from the fixed support; the limiting structure includes:

[0012] A rope, one end of which is connected to the movable support, and the other end of which is connected to a positioning stake for insertion into the construction surface;

[0013] The positioning stake is used to be installed on the side of the movable support facing away from the fixed support to restrict the movement of the movable support toward the fixed support.

[0014] In one possible implementation, the limiting structure further includes:

[0015] Multiple slide rails are provided on the construction surface of the fixed bracket facing the movable bracket; two adjacent slide rails are connected, and the movable bracket is slidably mounted on the slide rails;

[0016] One section of the slide rail at one end is connected to the fixed bracket, and the other section of the slide rail at the other end has a stop member adapted to connect with the movable bracket to limit the movement of the movable bracket away from the fixed bracket.

[0017] In one possible implementation, the slide rail has a protrusion and a groove at each end; the groove extends through the slide rail in the vertical direction to accommodate the protrusion.

[0018] Furthermore, the fixed bracket has a mating portion on the side facing the movable bracket, the mating portion being adapted to engage with the protrusion or the groove so that the fixed bracket and the slide rail are connected.

[0019] In one possible implementation, the damping element includes:

[0020] A connecting seat is fixedly mounted on the slide rail and located on the side of the movable bracket facing away from the fixed bracket; the connecting seat has a fixing nut, the axis of which is parallel to the direction of the connecting seat toward the movable bracket; and

[0021] The positioning platform is slidably mounted on the slide rail, and a hand-tightening bolt that is threadedly connected to the fixing nut is rotatably mounted on it.

[0022] In one possible implementation, the winding component includes:

[0023] A rotating roller, rotatably mounted on the fixed bracket in a horizontal direction; and

[0024] A rotating motor is mounted on the fixed bracket, and its power output end is connected to the end of the rotating roller.

[0025] In one possible implementation, the fixed bracket has a protective shell adapted to cover the rotating motor, and the upper side of the protective shell has two guide plates arranged side by side;

[0026] Both of the deflector plates are inclined to allow rainwater falling on the protective shell to flow outward.

[0027] In one possible implementation, the movable support has a lifting platform; the lifting platform has a slot for inserting the rain shield, and there is an adjustment structure between the lifting platform and the movable support so that the portion of the rain shield between the movable support and the fixed support is in an inclined state.

[0028] In one possible implementation, the adjustment structure includes:

[0029] Multiple threaded grooves are spaced apart on the movable bracket in the vertical direction;

[0030] A through hole, formed on the lifting platform, and adapted to communicate with any of the threaded grooves; and

[0031] A locking bolt is inserted into the through hole and is adapted to be threaded into the threaded groove to restrict the movement of the lifting platform relative to the movable support.

[0032] In one possible implementation, the movable support has rollers for contacting the construction surface.

[0033] In this embodiment, the distance between the movable and fixed supports can be changed by adjusting the position of the movable support relative to the fixed support to adapt to different stages of ground construction. Specifically, in the initial stage of ground construction, the fixed support is fixed to the construction surface, and the movable support is moved to a position that maintains a certain distance from the fixed support. Then, the position of the movable support is locked by a limiting structure. During the movement of the movable support, the rainproof belt can be released by the retracting assembly to keep it in a slack state, thereby avoiding restriction on the movement of the movable support. After the movable support is locked, the rainproof belt can be retracted by the retracting assembly to keep it taut and provide rain protection for the construction area.

[0034] In subsequent ground construction operations, if the construction area extends beyond the rain shield, the rain shield can be released to a slack state by using the rewind assembly and the limiting structure can be released to unlock the movable support, thereby moving the movable support again to the outside of the ground construction position; then, the rain shield can be retracted to a taut state by using the rewind assembly and the limiting mechanism can be used again to restrict the movement of the movable support.

[0035] The combined rain shelter mechanism for ground construction provided in this embodiment, compared with the prior art, can be adapted to construction areas that are gradually extended. That is, the versatility of this mechanism is improved by the adjustable position design of the movable support, so as to achieve the technical purpose of rain shelter for construction areas of different lengths and avoid affecting the efficiency of ground construction.

Therefore, they should not be construed as limitations on this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] Please refer to the following: Figures 1 to 10 The combined rain shelter mechanism for ground construction provided in this application will now be described. The combined rain shelter mechanism for ground construction proposed in this application includes a fixed support 1, a movable support 2, and a rain shelter 3.

[0053] Fixed support 1 is used to set at the starting position of ground construction, and movable support 2 is used to set at the position where ground construction is carried out. Specifically, both fixed support 1 and movable support 2 adopt a three-dimensional structure with a vertical cross section in the shape of a door, and both are fixed to the outside of the construction area, that is, the horizontal bar part is located outside the construction area, and the two vertical piles are fixed on both sides of the width direction of the construction area.

[0054] The movable support 2 has the freedom to slide relative to the construction surface, and the sliding direction is parallel to the arrangement direction of the fixed support 1 and the movable support 2, so that the movable support 2 can move toward or away from the fixed support 1, and shorten or lengthen the distance between the fixed support 1 and the movable support 2.

[0055] Based on this, the movable support 2 has a limiting structure 4 for restricting its movement; the limiting structure 4 enables the movable support 2 to be connected to the construction surface and / or the fixed support 1, so that the movement of the movable support 2 is restricted.

[0056] The rainproof belt 3 is made of flexible material and its width is greater than the width of the construction area. One end of the rainproof belt 3 is connected to the movable support 2, so that it is pulled as the movable support 2 moves away from the fixed support 1 and relaxes as the movable support 2 moves towards the fixed support 1. The other end of the rainproof belt 3 is fixedly mounted on the fixed support 1 by a winding assembly 5; specifically, the fixed support 1 has a winding assembly 5, and the winding assembly 5 is connected to the end of the rainproof belt 3. In actual use, the winding assembly 5 is used to retract or release the rainproof belt 3 so that the portion of the rainproof belt 3 between the fixed support 1 and the movable support 2 is in a taut state.

[0057] In this embodiment, by adjusting the position of the movable support 2 relative to the fixed support 1, the distance between the movable support 2 and the fixed support 1 can be changed to adapt to different stages of ground construction. Specifically, in the initial stage of ground construction, the fixed support 1 is fixed to the construction surface, and the movable support 2 is moved to a position that maintains a certain distance from the fixed support 1. Then, the position of the movable support 2 is locked by the limiting structure 4. During the movement of the movable support 2, the rainproof belt 3 can be released by the retracting assembly 5 to make the rainproof belt 3 slack, thereby avoiding restriction on the movement of the movable support 2. After the movable support 2 is locked, the rainproof belt 3 can be retracted by the retracting assembly 5 to make the rainproof belt 3 taut to provide rain protection for the construction area.

[0058] In subsequent ground construction operations, if the construction area extends to the outside of the rain shield 3, the rain shield 3 can be released to a slack state by the rewinding assembly 5 and the limiting structure 4 can be released to unlock the movable support 2, thereby moving the movable support 2 again to the outside of the ground construction position; then, the rain shield 3 can be retracted to a taut state by the rewinding assembly 5, and the movement of the movable support 2 can be restricted again by the limiting mechanism.

[0059] The combined rain shelter mechanism for ground construction provided in this embodiment, compared with the prior art, can be adapted to the gradually extending construction area. That is, the versatility of this mechanism is improved by the adjustable position design of the movable support 2, so as to achieve the technical purpose of rain shelter for construction areas of different lengths and avoid affecting the efficiency of ground construction.

[0060] In some embodiments, such as Figure 1 and Figure 6 As shown, the winding assembly 5 has a self-locking function so that the rainproof belt 3 in the taut state can restrict the movement of the movable support 2 away from the fixed support 1; that is, after the winding assembly 5 activates the self-locking function, the rainproof belt 3 cannot be pulled outward, thereby restricting the movement of the movable support 2.

[0061] In this embodiment, the limiting structure 4 includes a pull rope 41.

[0062] One end of the rope 41 is connected to the movable support 2, and the other end is connected to a positioning stake 411 for insertion into the construction surface.

[0063] In actual use, the positioning stake 411 is used to set on the side of the movable support 2 facing away from the fixed support 1 to restrict the movement of the movable support 2 toward the fixed support 1; at the same time, by reasonably controlling the distance between the positioning stake 411 and the movable support 2, it can be ensured that the pull rope 41 is in a taut state, so as to cooperate with the rainproof belt 3 to pull the movable support 2 in the opposite direction, and prevent the movable support 2 from tilting toward or away from the fixed support 1, thereby enhancing the structural stability of the movable support 2.

[0064] In some embodiments, such as Figure 1 and Figure 5 As shown, the limiting structure 4 also includes multiple slide rails 42.

[0065] Each slide rail 42 is installed on the construction surface of the fixed support 1 facing the movable support 2, and multiple slide rails 42 are arranged along the direction from the fixed support 1 to the movable support 2. Therefore, in the direction from the fixed support 1 to the movable support 2, adjacent slide rails 42 are connected, and the movable support 2 is slidably mounted on this slide rail 42. This allows for the sliding of the movable support 2 and also limits its direction of movement. As construction progresses, the slide rails 42 can be added to adapt to different construction area length requirements.

[0066] Furthermore, in the multi-section slide rail 42, the slide rail 42 near the fixed bracket 1 and located at the end is connected to the fixed bracket 1, and the slide rail 42 near the movable bracket 2 and located at the end has a stop 6 suitable for connecting with the movable bracket 2 to limit the movement of the movable bracket 2 away from the fixed bracket 1.

[0067] By adopting the above technical solution, the damping component 6 restricts the movement of the movable support 2 away from the fixed support 1, so as to cooperate with the self-locking function of the winding assembly 5, thereby ensuring the stability of restricting the movement of the movable support 2 away from the fixed support 1, while reducing the working pressure of the self-locking function, thereby reducing fatigue damage to the winding assembly 5.

[0068] It should be noted that when the winding assembly 5 does not have a self-locking function, this mechanism can still restrict the movement of the movable bracket 2 away from the fixed bracket 1 by using the multi-section slide rail 42 and the stop 6.

[0069] In some embodiments, such as Figure 5 As shown, the slide rail 42 has a protrusion 421 and a groove 422 at both ends; specifically, the protrusion 421 is located on the end face of the slide rail 42 and has a T-shaped cross-section; the groove 422 is opened at the other end of the slide rail 42 and extends through the slide rail 42 in the vertical direction to accommodate the protrusion 421.

[0070] In order to achieve the cooperation between the slide rail 42 and the fixed bracket 1, the fixed bracket 1 has a docking part 11 on the side facing the movable bracket 2. The docking part 11 is adapted to cooperate with the protrusion 421 or the groove 422 so that the fixed bracket 1 and the slide rail 42 are connected. In this embodiment, the structure of the docking part 11 is the same as that of the protrusion 421, so as to be adapted to cooperate with the groove 422 to achieve the technical purpose of connecting the fixed bracket 1 and the slide rail 42.

[0071] In some embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the actuator 6 includes a connecting seat 61 and a positioning stage 62.

[0072] The connecting seat 61 is fixedly mounted on the slide rail 42, specifically at the end of the slide rail 42 away from the fixed bracket 1, and on the side of the movable bracket 2 facing away from the fixed bracket 1. The connecting seat 61 has a fixing nut 611, the axis of which is parallel to the direction of the connecting seat 61 toward the movable bracket 2.

[0073] The positioning table 62 is slidably mounted on the slide rail 42, and a hand-tightening bolt 621 that is threadedly connected to the fixing nut 611 is rotatably mounted on it.

[0074] In actual use, the positioning platform 62 can be moved by rotating the hand screw 621 to abut against the side of the movable bracket 2 facing away from the fixed bracket 1, thereby restricting the movement of the movable bracket 2 away from the fixed bracket 1.

[0075] In some embodiments, such as Figure 3 and Figure 4 As shown, the winding assembly 5 includes a rotating roller 51 and a rotating motor 52.

[0076] The rotating roller 51 is positioned above the fixed support 1, with its axis parallel to the width direction of the construction area, and has the freedom to rotate relative to the fixed support 1 about its own central axis.

[0077] The rotating motor 52 is mounted on the fixed bracket 1, and its power output end is connected to the end of the rotating roller 51.

[0078] The rain shield 3 is connected to the outer wall of the rotating roller 51 so that when the rotating roller 51 rotates, the rain shield 3 can wrap around the rotating roller 51 or detach from the rotating roller 51.

[0079] In light of the foregoing, it should be noted that the self-locking function of the winding assembly 5 is achieved by utilizing the self-locking characteristics of the rotating motor 52. For example, a stepper motor achieves self-locking upon power-on by relying on the excitation holding torque of the stator winding; a reluctance self-locking motor automatically aligns and locks when power is off by relying on the principle of minimizing reluctance; and a permanent magnet self-locking synchronous motor generates periodic cogging torque to achieve positioning.

[0080] In some embodiments, such as Figure 3 As shown, the fixed bracket 1 has a protective shell 12 suitable for covering the rotating motor 52. The protective shell 12 can surround the outer perimeter of the rotating motor 52 to avoid interference from external dust and rain.

[0081] The upper side of the protective shell 12 has two guide plates 121 arranged side by side; both guide plates 121 are inclined so that rainwater falling on the protective shell 12 flows outward and avoids rainwater accumulation.

[0082] In some embodiments, such as Figure 6 and Figure 8 As shown, the movable support 2 has a lifting platform 7; the lifting platform 7 has a slot 71 for inserting the rain shield 3; it should be noted that in order to prevent the rain shield 3 from coming off the slot 71, it can be achieved by adhesive bonding; or, the lifting platform 7 is also provided with an anti-detachment structure for abutting against the rain shield 3 (not shown in the figure).

[0083] In this embodiment, the anti-detachment structure includes a through hole on the bottom surface of the lifting platform 7, which communicates with the slot 71 and has an internal thread structure on the inner wall of the through hole; correspondingly, the anti-detachment structure also includes a locking bolt that is threadedly connected to the through hole, which can be screwed into the slot 71 to abut against the rainproof belt 3 and prevent the rainproof belt 3 from detaching from the slot 71.

[0084] An adjustment structure 8 is provided between the lifting platform 7 and the movable support 2 so that the rainproof strip 3 between the movable support 2 and the fixed part is in an inclined state, thereby avoiding the accumulation of rainwater.

[0085] In some embodiments, such as Figure 8 As shown, the adjustment structure 8 includes multiple threaded grooves 81, through holes 82, and locking bolts 83.

[0086] Multiple threaded grooves 81 are spaced apart on the movable bracket 2 in the vertical direction.

[0087] A through hole 82 is provided on the lifting platform 7 and is adapted to communicate with any of the threaded grooves 81. Specifically, the lifting platform 7 is located inside the movable bracket 2 and has a downwardly extending protrusion. The through hole 82 is provided on this protrusion, and as the lifting platform 7 moves, the through hole 82 can coaxially communicate with any of the threaded grooves 81 provided inside the movable bracket 2.

[0088] The locking bolt 83 is inserted into the through hole 82 and is adapted to be threaded into the threaded groove 81 to restrict the movement of the lifting platform 7 relative to the movable bracket 2.

[0089] In some embodiments, such as Figure 1 , Figure 6 and Figure 9 As shown, the movable support 2 has rollers 21 for contacting the construction surface; specifically, a single movable support 2 has two vertical piles, and the bottom of each vertical pile is connected to a sliding seat. This sliding seat has four rollers 21, and two rollers 21 form a group. The two groups of rollers 21 are respectively set on the left and right sides (i.e., the width direction of the construction area) of the sliding seat. The two rollers 21 corresponding to each group are respectively set at the front and rear ends (i.e., the length direction of the construction area) of the sliding seat. The rotation axis of each roller 21 is parallel to the width direction of the construction area.

[0090] The slide rail 42 proposed in conjunction with the above content has two guide grooves, and two sets of rollers 21 are respectively embedded in the two guide grooves to realize the sliding setting of the movable bracket 2 and ensure the convenience and stability of the adjustment of the movable bracket 2.

[0091] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
