Description

Technical Field

[0001] The invention relates to the technical field of bridge transportation, and in particular to a motor-driven beam transport vehicle control device. Background Art

[0002] The beam transporter is a supporting equipment for the construction of the bridge erection machine. It is a special vehicle that transports the reinforced concrete beam bridge deck prefabricated in the prefabrication plant or the bridge site to the bridge erection machine. It is divided into track-type and tire-type. Due to its heavy load, it is required to be low in height to reduce the overall height of the bridge erection machine.

[0003] When constructing a bridge, a beam transporter is needed to move the prefabricated reinforced concrete bridge. When transporting some long prefabricated beams, an active vehicle and a passive vehicle are often used for transportation. Since the prefabricated beams need to be placed on the frame of the beam transporter, if a supporting structure is installed above it, it is easy to block the prefabricated beams, resulting in restrictions on the placement of the prefabricated beams. Therefore, the beam transporter only supports the bottom of the prefabricated beams and lacks a structure to limit the ends of the prefabricated beams. Therefore, when the vehicle turns, the prefabricated beams are prone to side shifting, resulting in uneven force between the two vehicles. At the same time, when the vehicle goes uphill or downhill, if the slope is large, it is easy to cause a small displacement of the prefabricated beams, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a motor-driven beam transport vehicle control device.

[0005] To achieve the above object, the present invention provides the following technical solution: a motor-driven beam transport vehicle control device, comprising a beam transport vehicle body and a prefabricated bridge, and further comprising:

[0006] A support structure, which is arranged on the beam transport vehicle body and is used to limit the center of gravity shift of the prefabricated bridge;

[0007] an adjustment assembly disposed on the support structure for controlling the position of the precast bridge support;

[0008] The supporting structure comprises a groove, the groove is arranged on both sides of the top of the beam transport vehicle body, the inner wall of the groove is provided with a slide groove, the inside of the slide groove is slidably connected with a movable platform, a double-axis motor is installed at the bottom of the movable platform, a rotating bracket is installed at the top output shaft of the double-axis motor, a fixing piece is fixed on the top of the rotating bracket, a movable bracket is hinged on the inner side of the fixing piece, two groups of first hydraulic cylinders are installed at the end of the movable bracket, a support plate is installed at the end of the first hydraulic cylinder, and a second hydraulic cylinder is hinged on one side of the rotating bracket;

[0009] Among them, the adjustment component includes a long plate, which is installed at the bottom of the inner cavity of the groove, a gear is installed on the bottom output shaft of the dual-axis motor, a notch is opened inside the beam transport vehicle body, a movable rod is sleeved inside the notch, the top end of the movable rod passes through the notch and is installed with a support platform, the bottom end of the movable rod passes through the notch and is installed with an extrusion piece, a fixing ring is fixed on the outer surface of the movable rod, a return spring is sleeved on the outer surface of the movable rod, a plurality of groups of limit members are fixed to the bottom of the extrusion piece, and a plurality of groups of card slots are opened on the top of the movable platform.

[0010] As a preferred solution of the present invention, the beam transport vehicle body is divided into two groups, the two groups of beam transport vehicle bodies are respectively an active vehicle and a passive vehicle, and the two ends of the prefabricated bridge are respectively located on the two groups of beam transport vehicle bodies.

[0011] As a preferred solution of the present invention, the top of the support platform is made of a steel plate with a rough surface, and the bottom surface of the prefabricated bridge is in extrusion contact with the support platform.

[0012] As a preferred solution of the present invention, one side of the long plate is tooth-shaped, and the gear is meshingly connected with the long plate.

[0013] As a preferred solution of the present invention, the top end of the second hydraulic cylinder is hinged to two groups of first hydraulic cylinders at the same time, and one side of the support plate is in extrusion contact with the end of the prefabricated bridge.

[0014] As a preferred solution of the present invention, the extrusion member is slidably connected to the beam transport vehicle body, and the limit member is movably engaged with the engaging groove.

[0015] As a preferred solution of the present invention, the rotating bracket is rotatably connected to the movable platform, and the movable platform, rotating bracket, fixing member and movable frame are all made of high-strength materials. The height of the fixing member and the first hydraulic cylinder in the initial state is lower than the height of the support platform.

[0016] As a preferred solution of the present invention, there is a gap between the support platform and the beam transport vehicle body. When the prefabricated bridge presses the support platform, the support platform is supported by the beam transport vehicle body, and the limit piece is engaged with the prefabricated bridge.

[0017] As a preferred solution of the present invention, the return spring is elastically supported between the notch and the fixed ring, and the moving speed between the two groups of beam transport vehicle bodies remains consistent.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can control the rotation of the gear through the operation of the dual-axis motor. At this time, the movable platform can be controlled to move left and right through the cooperation between the gear and the long board and the movable platform and the slide groove. At the same time, through the operation of the second hydraulic cylinder, the first hydraulic cylinder can be controlled to drive the movable frame to rotate upward along the inner side of the fixed part. At this time, the rotation of the rotating bracket is controlled by the dual-axis motor, and the position of the first hydraulic cylinder toward the prefabricated bridge can be controlled. Therefore, through the operation of the first hydraulic cylinder, the support plate can be controlled to squeeze the prefabricated bridge, and then both ends of the prefabricated bridge can be supported at the same time, thereby improving its stability when the beam transport vehicle body goes uphill or downhill.

[0020] 2. In the present invention, since the initial height of the first hydraulic cylinder is lower than the height of the rotating bracket, and the rotating bracket is used to support the prefabricated bridge, the setting of the first hydraulic cylinder does not affect the placement of the prefabricated bridge, and from the perspective of the rear end of the beam transport vehicle body, the first hydraulic cylinder is in a horizontal state on the top of the beam transport vehicle body, and the prefabricated bridge is in a longitudinal position. At the same time, the position of the first hydraulic cylinder can be adjusted, so the first hydraulic cylinder will not be blocked by the prefabricated bridge when rotating upward, and then the first hydraulic cylinder is rotated left and right and the position is adjusted, which is convenient for controlling the support plate to support the end of the prefabricated bridge and reduce the occupied space.

[0021] 3. The present invention uses the gap between the support platform and the beam transport vehicle body to create pressure on the support platform when the prefabricated bridge is placed on top of the support platform. At this time, the support platform will drive the extrusion parts and the limit parts to limit the movable platform through the movable rod. Since the support strength is poor due to the meshing of the gears and the long plates, the weight of the prefabricated bridge itself is used to control the limit parts to limit the movable platform, so that the support of the prefabricated bridge by the support plate is more stable.

[0022] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, the present invention provides a motor-driven beam transport vehicle control device, comprising a beam transport vehicle body 1 and a prefabricated bridge 22, and further comprising:

[0033] A support structure, which is arranged on the beam transport vehicle body 1 and is used to limit the center of gravity shift of the prefabricated bridge 22;

[0034] an adjustment assembly, which is disposed on the support structure and is used to control the position of the support for the prefabricated bridge 22;

[0035] The supporting structure includes a groove 2, which is arranged on both sides of the top of the beam transport vehicle body 1. A slide groove 3 is opened on the inner wall of the groove 2. A movable platform 4 is slidably connected inside the slide groove 3. A double-axis motor 5 is installed at the bottom of the movable platform 4. A rotating bracket 6 is installed on the top output shaft of the double-axis motor 5. A fixing piece 7 is fixed on the top of the rotating bracket 6. A movable frame 8 is hinged on the inner side of the fixing piece 7. Two groups of first hydraulic cylinders 9 are installed at the end of the movable frame 8. A support plate 11 is installed at the end of the first hydraulic cylinder 9. A second hydraulic cylinder 10 is hinged on one side of the rotating bracket 6.

[0036] Among them, the adjustment component includes a long plate 12, which is installed at the bottom of the inner cavity of the groove 2, a gear 13 is installed on the bottom output shaft of the dual-axis motor 5, a slot 14 is opened inside the beam transport vehicle body 1, and a movable rod 15 is sleeved inside the slot 14. The top of the movable rod 15 passes through the slot 14 and is installed with a support platform 16. The bottom end of the movable rod 15 passes through the slot 14 and is installed with an extrusion piece 19. A fixing ring 17 is fixed to the outer surface of the movable rod 15. A reset spring 18 is sleeved on the outer surface of the movable rod 15. Several groups of limit members 20 are fixed to the bottom of the extrusion piece 19, and several groups of card slots 21 are opened on the top of the movable platform 4.

[0037] By the operation of the double-axis motor 5, the gear 13 can be controlled to rotate. At this time, the gear 13 and the long board 12 and the movable platform 4 and the slide 3 can be used to control the movable platform 4 to move left and right. At the same time, by the operation of the second hydraulic cylinder 10, the first hydraulic cylinder 9 can be controlled to drive the movable frame 8 to rotate upward along the inner side of the fixing member 7. At this time, the rotating bracket 6 is controlled to rotate by the double-axis motor 5, and the position of the first hydraulic cylinder 9 toward the prefabricated bridge 22 can be controlled. Therefore, by the operation of the first hydraulic cylinder 9, the support plate 11 can be controlled to squeeze the prefabricated bridge 22, and then both ends of the prefabricated bridge 22 can be supported at the same time, thereby improving the stability of the beam transport vehicle body 1 when it goes uphill or downhill.

[0038] like Figure 2 As shown, the beam transport vehicle body 1 is divided into two groups, the two groups of beam transport vehicle bodies 1 are respectively an active vehicle and a passive vehicle, and the two ends of the prefabricated bridge 22 are respectively located on the two groups of beam transport vehicle bodies 1.

[0039] When the two ends of the prefabricated bridge 22 are supported by the beam transport vehicle body 1, the length of the part of the prefabricated bridge 22 located directly above each group of beam transport vehicle bodies 1 is inevitably different. Therefore, the gear 13 can be controlled to rotate through the dual-axis motor 5, so that the gear 13 and the long plate 12 cooperate to drive the movable platform 4 to slide along the inside of the slide groove 3, and the position of the first hydraulic cylinder 9 supporting the prefabricated bridge 22 can be adjusted, so that the angles of the two groups of first hydraulic cylinders 9 supporting the prefabricated bridge 22 are consistent, thereby improving its stability. In addition, the two ends of the prefabricated bridge 22 are supported synchronously, which can reduce the side shift when turning.

[0040] like Figure 2 , 3 As shown, the top of the support platform 16 is made of a steel plate with a rough surface, and the bottom surface of the prefabricated bridge 22 is in compression contact with the support platform 16 .

[0041] Through the design of the support platform 16, since the support platform 16 is in direct contact with the prefabricated bridge 22, a material that is not easily deformed is required, and steel itself has a large friction force, making its surface rougher can further increase the friction between it and the prefabricated bridge 22, making the prefabricated bridge 22 less likely to move.

[0042] like Figure 4 As shown, one side of the long plate 12 is tooth-shaped, and the gear 13 is meshed and connected with the long plate 12 .

[0043] Through the cooperation between the long board 12 and the gear 13, when the long board 12 rotates, it will roll along the tooth groove of the gear 13. At the same time, through the cooperation between the movable platform 4 and the slide groove 3, when the long board 12 rotates, the movable platform 4 will slide along the inner side of the slide groove 3, so as to facilitate the control of the position of the first hydraulic cylinder 9.

[0044] like Figure 7 As shown, the top end of the second hydraulic cylinder 10 is hinged to the two groups of first hydraulic cylinders 9 at the same time, and one side of the support plate 11 is in compression contact with the end of the prefabricated bridge 22 .

[0045] Through the cooperation between the second hydraulic cylinder 10 and the first hydraulic cylinder 9 , the lifting angle of the first hydraulic cylinder 9 can be controlled, so that the support plate 11 can be controlled to move by the first hydraulic cylinder 9 so that it can support the end of the prefabricated bridge 22 .

[0046] like Figure 6 As shown, the extrusion member 19 is slidably connected to the beam transport vehicle body 1 , and the limiting member 20 is movably engaged with the clamping groove 21 .

[0047] The movable platform 4 can be limited by the cooperation between the limiting member 20 and the card slot 21 , so that the position of the rotating bracket 6 and the movable frame 8 can be limited by the movable platform 4 , so that the support plate 11 can stably support the prefabricated bridge 22 .

[0048] like Figure 7 As shown, the rotating bracket 6 is rotatably connected to the movable platform 4. The movable platform 4, the rotating bracket 6, the fixing member 7 and the movable frame 8 are all made of high-strength materials. The height of the fixing member 7 and the first hydraulic cylinder 9 in the initial state is lower than the height of the support platform 16.

[0049] Through the design of the first hydraulic cylinder 9, since its initial height is lower than the height of the rotating bracket 6, and the rotating bracket 6 is used to support the prefabricated bridge 22, the setting of the first hydraulic cylinder 9 does not affect the placement of the prefabricated bridge 22, and from the perspective of the rear of the beam transport vehicle body 1, the first hydraulic cylinder 9 is in a horizontal state on the top of the beam transport vehicle body 1, and the prefabricated bridge 22 is in a longitudinal position. At the same time, the position of the first hydraulic cylinder 9 can be adjusted, so the first hydraulic cylinder 9 will not be blocked by the prefabricated bridge 22 when rotating upward, and then the first hydraulic cylinder 9 is rotated left and right and the position is adjusted, which is convenient for controlling the support plate 11 to support the end of the prefabricated bridge 22, and will not hinder the placement of the prefabricated bridge 22.

[0050] like Figure 2 , 6 As shown, there is a gap between the support platform 16 and the beam transport vehicle body 1. When the prefabricated bridge 22 presses the support platform 16, the support platform 16 is supported by the beam transport vehicle body 1, and the limiting member 20 is engaged with the prefabricated bridge 22.

[0051] Through the gap between the support platform 16 and the beam transport vehicle body 1, when the prefabricated bridge 22 is placed on the top of the support platform 16, pressure will be exerted on the support platform 16. At this time, the support platform 16 will drive the extrusion member 19 and the limit member 20 to limit the movable platform 4 through the movable rod 15. Since the supporting strength is poor due to the engagement of the gear 13 with the long plate 12, the weight of the prefabricated bridge 22 itself is used to control the limit member 20 to limit the movable platform 4, which can achieve a stable positioning effect.

[0052] like Figure 2 , 6 As shown, the return spring 18 is elastically supported between the notch 14 and the fixing ring 17, and the moving speed between the two groups of beam transport vehicle bodies 1 remains consistent.

[0053] Through the design of the reset spring 18, the fixing ring 17 has good elastic reset performance. At this time, since the reset spring 18 is in a compressed state, it will apply an elastic force to the fixing ring 17, so that when the prefabricated bridge 22 is separated from the support platform 16, the limit member 20 is driven to separate from the slot 21, and the movable platform 4 can be released from the limit.

[0054] Working principle:

[0055] First, when loading the prefabricated bridge 22, the prefabricated bridge 22 is suspended above the support platform 16 without direct contact with the support platform 16, and then the dual-axis motor 5 is started to control the gear 13 to rotate. At this time, through the cooperation between the gear 13 and the long board 12, and the cooperation between the movable platform 4 and the slide 3, the movable platform 4 will be controlled to slide along the inside of the slide 3, so that the first hydraulic cylinder 9 can be controlled to move to a position away from the end of the prefabricated bridge 22. Then, through the operation of the second hydraulic cylinder 10, the cooperation between the second hydraulic cylinder 10 and the first hydraulic cylinder 9 and the movable frame 8 and the fixing part 7 will control the first hydraulic cylinder 9 to lift up. At this time, the dual-axis motor 5 can be controlled The rotating bracket 6 rotates to make the support plate 11 face the end of the prefabricated bridge 22. At this time, it can be judged that the first hydraulic cylinder 9 can control the support plate 11 to squeeze the prefabricated bridge 22 when it is running. If not, the gear 13 is controlled to rotate again, and the position of the first hydraulic cylinder 9 is adjusted. Then the prefabricated bridge 22 is slowly placed. When the prefabricated bridge 22 squeezes the support platform 16, the extrusion member 19 will be driven downward by the movable rod 15 to control the limit member 20 to engage with the slot 21. At this time, the movable platform 4 will be in a fixed state. Finally, the first hydraulic cylinder 9 is used to control the support plate 11 to move obliquely upward, so that it supports the end of the prefabricated bridge 22 and improves its stability.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
