[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The guardrail installation device of an embodiment of the present application is described below with reference to the accompanying drawings.

[0029] The guardrail installation equipment provided in the embodiment of the present application can be used in related equipment for handling and transferring objects, for example, transporting the guardrail body from a transport vehicle to an installation location and adjusting it to facilitate installation by relevant staff.

[0030] like Figure 1 and Figure 2 As shown, the guardrail installation device of the embodiment of the present application may include a fixed plate 1, a mounting frame 2, a movable component 3 and an installation component 4.

[0031] The fixing plate 1 is installed on a vehicle that transports the guardrail body 6 .

[0032] It should be noted that mounting holes are provided at the four corners of the fixing plate 1 , and the fixing plate 1 is locked on the vehicle by fastening bolts passing through the mounting holes. The specific installation position can be set in the transport compartment of the vehicle.

[0033] Two mounting frames 2 arranged opposite to each other are respectively pivotally arranged on the fixing plate 1 .

[0034] The mounting frame 2 is connected to the fixing plate 1 via a hydraulic rod 13, and the hydraulic rod 13 is used to drive the mounting frame 2 to rotate. As the hydraulic rod 13 is extended, the mounting frame 2 is lifted up and rotated until it reaches the target position.

[0035] It should be noted that the connection between the hydraulic rod 13 and the mounting frame 2 is close to the rotation axis of the mounting frame 2, so that the hydraulic rod 13 can drive the mounting frame 2 to rotate in a larger range through a smaller extension amount.

[0036] The moving component 3 is arranged on the mounting frame 2, and the mounting component 4 is arranged on the moving end of the moving component 3. The moving component 3 is used to drive the mounting component 4. The hydraulic rod 13, the moving component 3, and the mounting component 4 are respectively connected to the controller 5.

[0037] It should be noted that there are two moving components 3 , and the two moving components 3 are respectively arranged on opposite surfaces of two mounting frames 2 to improve the stability when the moving component 3 drives the mounting component 4 to move.

[0038] It can be understood that the two moving components 3 described in the embodiment of the present application are synchronously connected to the controller 5 to ensure that the two moving components 3 can synchronously drive the installation component 4 to move, thereby avoiding the two moving components 3 from causing force damage to the installation component 4 due to movement deviation.

[0039] Specifically, Figure 3 and Figure 4 As shown, the installation assembly 4 described in this embodiment may include a connecting plate 41 , a placement plate 42 , a first telescopic rod 43 , a clamping device 44 and a roller 45 .

[0040] Among them, the connecting plate 41 is connected to the moving end of the moving component 3, the placing plate 42 is arranged above the connecting plate 41, and is connected to the connecting plate 41 through the first telescopic rod 43, the first telescopic rod 43 is used to push the placing plate 42 to adjust the position of the placing plate 42, the clamping device 44 is movably set on the placing plate 42, and the roller 45 is rotatably set on the placing plate 42, wherein the clamping end of the clamping device 44 and the roller 45 jointly clamp the guardrail body 6.

[0041] It should be noted that the connecting plate 41 described in the embodiment of the present application is a U-shaped plate, and both sides of the connecting plate 41 are respectively connected to the moving ends of the two moving components 3.

[0042] To clearly illustrate the above embodiment, Figure 5 As shown, in one embodiment of the present application, the clamping device 44 may include a second telescopic rod 441 , a second slide rail 442 , a baffle 443 and a pressing plate 444 .

[0043] Among them, a second slide groove 422 is arranged on the side of the placement plate 42 close to the connecting plate 41, the second slide rail 442 is slidably connected to the second slide groove 422, the baffle 443 is arranged on the second slide rail 442, the second telescopic rod 441 is installed on the placement plate 42, and the telescopic end of the second telescopic rod 441 is connected to the baffle 443, and the clamping plate 444 is arranged at the end of the second slide rail 442, wherein the clamping plate 444 is a folding plate, wherein the roller 45 is arranged on the side of the placement plate 42 away from the connecting plate 41, and the clamping plate 444 and the roller 45 are used to clamp the guardrail body 6 together.

[0044] It should be noted that the length of the placement plate 42 is greater than the distance between the two mounting frames 2, so that when the guardrail body 6 is placed on the placement plate 42, the placement plate 42 can protect the mounting frame 2 and the moving component 3, thereby preventing the guardrail body 6 from colliding with the mounting frame 2 and the moving component 3 during movement, thereby causing damage.

[0045] In addition, the height dimension of the placement plate 42 is smaller than the height dimension of the guardrail body 6 , so that when the clamping plate 444 clamps the guardrail body 6 , the clamping plate 444 will not be unable to descend to the clamping position due to the height dimension of the placement plate 42 .

[0046] In an embodiment of the present application, the rotation of the mounting frame 2 can be controlled by extending and retracting the hydraulic rod 13, so that the mounting frame 2 can be rotated from a horizontal state to a vertical state, and the mounting component 4 can be driven to move to the installation height by the moving component 3. By adjusting the mounting component 4, the guardrail can be adjusted to meet the installation requirements, and after the installation is completed, the clamping can be released and reset.

[0047] Specifically, when installing guardrails on the middle road or on both sides of the road, relevant staff drive transport vehicles to the installation site.

[0048] After the transport vehicle reaches the installation site and adjusts the orientation of the vehicle (the specific orientation position requires that the guardrail installation device in the embodiment of the present application is close to the installation site), the relevant staff will place the guardrail body 6 on the transport vehicle on the placement plate 42. For example, the relevant staff can lift and place the guardrail body 6 manually or using a lifting machine.

[0049] Then, as shown in Figure 7(a), the controller 5 controls the clamping device 44 to clamp the guardrail body 6, that is, the controller 5 controls the second telescopic rod 441 to start to contract from the original extended state, thereby driving the baffle 443 to move, so that the second slide rail 442 moves in the second slide groove 422, and finally the clamping plate 444 moves toward the roller 45 until the guardrail body 6 is clamped between the clamping plate 444 and the roller 45.

[0050] Next, as shown in FIG. 7( b ), the relevant staff controls the hydraulic rod 13 to extend through the controller 5 , and the extended hydraulic rod 13 lifts the mounting frame 2 , so that the mounting frame 2 starts to rotate until it reaches a preset position (the preset position is the position of the mounting frame 2 when it is vertical).

[0051] After the mounting frame 2 reaches the preset position, the relevant staff controls the moving component 3 to start moving through the controller 5, so that the mounting component 4 follows the moving component 3 to move to the installation height (the installation height is the installation height of the guardrail body 6, that is, the height of the guardrail body 6 installed on the column. The installation height can be preset in advance by the relevant staff according to the type of the guardrail body).

[0052] Then the relevant staff makes adjustments based on the position deviation between the guardrail body 6 and the column. First, the controller 5 is used to control the extension of the second telescopic rod 441, so that the guardrail body 6 moves horizontally following the placement plate 42 until the installation position of the column and the installation position of the guardrail body are coaxial. Then the relevant staff loosens the clamping plate 444 on the clamping device 44 through the controller 5.

[0053] Then the relevant staff holds the guardrail body 6 and pulls the guardrail body 6, so that the guardrail body 6 moves on the roller 45 until the installation position on the guardrail body 6 is inserted into the installation position of the column and locked by the relevant staff.

[0054] Finally, the relevant staff controls the moving component 3 to continue to move downward, so that the roller 45 is separated from the guardrail body 6, and then controls the second telescopic rod 441 to retract through the controller 5, so that the installation component 4 is separated from the installed guardrail body 6, and then the installation component 4 continues to reset following the moving component 3, and controls the hydraulic rod 13 to retract, so that the mounting frame 2 is reset.

[0055] After the mounting frame 2 and the moving assembly 3 are reset, the transport vehicle moves forward a distance of a guardrail body 6 to install the next guardrail body 6 .

[0056] It should be noted that, in order to improve the stability of the installation component 4 when following the movement of the moving component 3, a first slide groove 201 is opened on the installation frame 2, and a first slide rail 421 is provided on the placement plate 42, wherein the first slide rail 421 is slidably connected to the first slide groove 201.

[0057] In one embodiment of the present application, Figure 1 and Figure 2 As shown, two relatively arranged mounting frames 2 can be pivotally arranged on the fixed plate 1 respectively. Specifically, a supporting frame 12 is arranged on the fixed plate 1 , and the mounting frames 2 are pivotally connected to the supporting frame 12 .

[0058] A limiting frame 11 is disposed on the fixing plate 1 , and the limiting frame 11 is disposed away from the supporting frame 12 , so that when the mounting frame 2 rotates to a horizontal state, the limiting frame 11 supports and limits the rotating mounting frame 2 .

[0059] It should be noted that the limiting frame 11 includes a horizontal plate and a vertical plate.

[0060] The vertical plate is arranged on the fixed plate 1 , and the horizontal plate is vertically arranged on the vertical plate. When the mounting frame 2 rotates to a horizontal state, the horizontal plate supports and limits the mounting frame 2 . The controller 5 is arranged on the outer wall of the vertical plate of the limiting frame 11 .

[0061] Specifically, after the relevant staff places the guardrail body 6 on the placement plate 42 and clamps it through the clamping device 44, the relevant staff controls the hydraulic rod 13 to extend through the controller 5, and the hydraulic rod 13 lifts the mounting frame 2, and the mounting frame 2 rotates along the axial connection with the support frame 12, and the other end of the mounting frame 2 leaves the limit frame 11 until the entire mounting frame 2 rotates to the vertical direction.

[0062] After the installation of the guardrail body 6 is completed, the relevant staff controls the hydraulic rod 13 to retract through the controller 5, and the corresponding mounting frame 2 begins to reset until one end of the mounting frame 2 contacts the horizontal plate of the limiting frame 11, and the hydraulic rod 13 stops retracting.

[0063] In one embodiment of the present application, Figure 6As shown, the moving assembly 3 includes a mounting chamber 31 , a driving motor 32 , a lead screw 33 and a lead screw slider 34 .

[0064] The mounting chamber 31 is arranged on the mounting frame 2, and a through slot is provided on the mounting chamber 31. The driving motor 32 is arranged outside the mounting chamber 31. The lead screw 33 is arranged inside the mounting chamber 31 and connected to the driving motor 32. The lead screw slider 34 is arranged on the lead screw 33, and the end of the lead screw slider 34 moves in the through slot.

[0065] It should be noted that the specific way of connecting the connecting plate 41 to the moving component 3 is that the connecting plate 41 is connected to the screw slider 34, and the connecting plate 41 can be fixed on the screw slider 34 by bolt locking to facilitate later disassembly and maintenance.

[0066] Specifically, after the guardrail body 6 is clamped on the mounting assembly 4 and the mounting frame 2 is rotated to a vertical state, the guardrail body 6 needs to be transported from the top of the mounting frame 2 to the installation height.

[0067] That is, the relevant staff controls the driving motor 32 to rotate through the controller 5, and the driving motor 32 drives the screw 33 to rotate, so that the screw slider 34 moves on the screw 33, and correspondingly, the screw slider 34 drives the installation component 4 to move to the installation height.

[0068] After the guardrail body 6 is installed, the moving component 3 drives the installation component 4 to reset, that is, the controller 5 controls the driving motor 32 to reverse, so that the screw 33 reverses, thereby causing the screw slider 34 to move in the opposite direction on the screw 33 to achieve reset.

[0069] As a possible situation, in the resetting stage, the controller 5 can first control the hydraulic rod 13 to retract so that the mounting frame 2 is reset to a horizontal state, and then control the moving component 3 to drive the mounting component 4 to reset, so as to reduce the load of the moving component 3 when resetting and increase the service life of the moving component 3.

[0070] It should be noted that a protective shell is provided outside the driving motor 32, and the protective shell can be fixed to the mounting frame 2 by bolt locking to prevent collision during the movement of the guardrail body 6, thereby preventing damage to the driving motor 32. The protective shell can also be waterproof and dustproof, thereby increasing the service life of the driving motor 32.

[0071] In summary, the guardrail installation device of the embodiment of the present application can clamp and move the guardrail body through the installation component, which not only reduces the manual workload of installation, but also can fine-tune the installation position of the guardrail body, making the installation more convenient.
