Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction material transportation, in particular to a culvert pipe transportation device. BACKGROUND

[0002] In municipal infrastructure construction, culvert pipes are widely used building materials for constructing drainage systems, bridge culverts and other structures, and the transportation of culvert pipes is an important task in municipal construction, and its efficiency directly affects the progress and cost of the entire project.

[0003] Currently, when culvert pipes are transported, the following stages need to be gone through, namely loading culvert pipes, transporting culvert pipes and unloading culvert pipes. During the loading stage of culvert pipes, personnel need to hoist the culvert pipes by hoisting equipment, and in order to control the maximum transportation of culvert pipes, personnel will control the hoisting equipment to move back and forth near the transport vehicle to adjust the stacking position of the culvert pipes, and during the unloading of culvert pipes, the hoisting equipment needs to be used to hoist the culvert pipes one by one, and the hoisting equipment also needs to be controlled to move back and forth.

[0004] The traditional culvert pipe transportation method mainly relies on manual labor and simple mechanical equipment. The related technical scheme involves a culvert pipe transportation device for municipal construction. When the device is used, the culvert pipes can be transported by the lifting assembly, the clamping assembly can be moved downward into the culvert pipe by the extension assembly, the culvert pipes can be clamped conveniently, the culvert pipes can be clamped during transportation by the clamping assembly, the clamping plate no longer needs to be manually pushed one by one by the cooperation of the first wedge and the first contact rod, which is more convenient for people to use, the clamping plate can be automatically loosened by the cooperation of the second wedge and the second contact rod, and the mounting plate can be clamped according to the needs of people by the cooperation of the second fixed plate and the insertion rod. Although the device can unload the culvert pipes on the transport vehicle, it is basically the same as the existing hoisting equipment principle, only assisting personnel in unloading the culvert pipes during the unloading stage, and it cannot assist personnel during the loading and transportation of culvert pipes. Since the device can only unload the culvert pipes, the device needs to be moved one by one before the culvert pipes can be unloaded when the device assists personnel in unloading the culvert pipes.

[0005] Therefore, how to avoid the need for hoisting equipment to move back and forth during the loading and unloading of culvert pipes, and thereby improve the loading and unloading efficiency of culvert pipes, is a technical problem that needs to be solved by those skilled in the art at present.

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0038] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inner" and "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0039] The present application aims to provide a culvert conveying device, which can avoid the need for hoisting equipment to move back and forth during loading and unloading of the culvert, thereby improving the loading and unloading efficiency of the culvert.

[0040] To achieve the above object, the present application provides the following technical solutions.

[0041] Please refer to Figures 1 to 5 The present embodiment provides a culvert conveying device, which comprises a connecting piece 200 and two support pieces, each of which comprises a shell 100 provided with a placing cavity 110 for accommodating a culvert, and the two placing cavities 110 are located on opposite sides of the two support pieces, a plurality of inclined plates 120 at a certain angle with the horizontal plane are arranged in the placing cavities 110, all the inclined plates 120 are arranged in an up-down interval and staggered manner, so that the culverts can pass through all the inclined plates 120 in sequence to the slope 130 on the inner side of the bottom of the shell 100, and the bottom and one side of the shell 100 are provided with side plates 140 with through holes; the connecting piece 200 is arranged in the corresponding through hole to connect the two support pieces.

[0042] When the support piece is fixed to the transport vehicle, the culvert is supported by the inclined plates 120 between the two shells 100, and when the personnel load the culvert by the hoisting device, the culvert is only moved to a high place at a fixed position by the hoisting device and then put into the uppermost inclined plate 120, because the inclined plates 120 are arranged obliquely, when the culvert is placed on the inclined plate 120, the culvert is guided by the inclined plate 120 to roll from top to bottom between the two shells 100, so that the culvert gradually rolls to the bottom of the shell 100, until the culvert is stacked between the two shells 100, when unloading, the bottom culvert is only taken off at a fixed unloading point, and the remaining culverts will roll to the bottom of the shell 100 under the action of their own gravity, so that the personnel can move the culvert by the hoisting device without controlling the hoisting device to move back and forth near the transport vehicle, which can avoid the hoisting device moving back and forth during loading and unloading, thereby improving the loading and unloading efficiency of the culvert.

[0043] Please refer to Figure 6 Preferably, the shell 100 is rotatably connected with a discharge plate 150 capable of shielding the placing cavity 110 on one side, and a first electric push rod 300 connected to the discharge plate 150 is arranged on the side of the shell 100 away from the inclined plate 120, and the first electric push rod 300 is capable of extending and retracting to adjust the angle between the discharge plate 150 and the slope 130, so that the culvert moves to the discharge plate 150 through the slope 130.

[0044] It can be understood that the shell 100 is rotatably connected with a discharge plate 150 capable of shielding the placing cavity 110 on one side, the bottom of the discharge plate 150 is connected to the shell 100 through a rotating shaft, and a first electric push rod 300 capable of extending and retracting to adjust the angle between the discharge plate 150 and the slope 130 is arranged on the side of the shell 100 away from the inclined plate 120.

[0045] When the culvert is loaded, the first electric push rod 300 drives the unloading plate 150 to rotate along the rotating shaft to block the placing cavity 110, so as to prevent the culvert from separating from the placing cavity 110 during the loading process; when the culvert is unloaded, the first electric push rod 300 drives the unloading plate 150 to rotate along the rotating shaft to be lower than the height of the slope 130, so that the culvert falls along the slope 120 and then falls along the unloading plate 150 out of the placing cavity 110, that is, the total path of all culverts from loading to unloading is the same, that is, falling from the uppermost inclined plate 120 to the unloading plate 150.

[0046] In this embodiment, when the unloading plate 150 blocks the placing cavity 110, the top of the unloading plate 150 and the top of the shell 100 are the same height, and the size of the unloading plate 150 can also be adjusted according to actual needs, for example, the shell 100 is provided with an opening only on one side below, and the unloading plate 150 with a length consistent with the distance from the bottom of the slope 130 to the lowermost inclined plate 120 is installed.

[0047] Preferably, the end of the unloading plate 150 away from the slope 130 is rotatably provided with a baffle 160, and the unloading plate 150 is provided with a second electric push rod 400 connected to the baffle 160, and the second electric push rod 400 can drive the baffle 160 to rotate to limit the culvert passing through the slope 130 from separating from the unloading plate 150.

[0048] When the transport vehicle drives the culvert conveying device to move to the unloading point, the first electric push rod 300 drives the unloading plate 150 to rotate around the shell 100, so that the unloading plate 150 cannot block the placing cavity 110, until the unloading plate 150 is inclined and in contact with the ground. Since the inclined plate 120 is inclinedly arranged and cooperates with the slope 130, the culverts between the two shells 100 are successively slid down, and the baffle 160 at the end of the unloading plate 150 away from the slope 130 controls the culvert to stop unloading or continue unloading through the second electric push rod 400.

[0049] Preferably, the bottom outside of the shell 100 is provided with a clamping assembly and a jacking rod 180 which are spaced apart, the jacking rod 180 can support the support member to be horizontal relative to the horizontal plane, and the clamping assembly is used to fix the support member adjusted by the jacking rod 180.

[0050] It can be understood that the bottom of the shell 100 is also provided with a clamping assembly and a jacking rod 180 which are spaced apart, the jacking rod 180 contacts the vehicle to support the support member, and the clamping assembly is used to fix the support member to prevent the support member from moving and causing damage to the culvert.

[0051] Preferably, the side of the shell 100 away from the inclined plate 120 is provided with a level 190 to detect the inclination degree of the support member, and the jacking rod 180 is a hydraulic rod, and the piston rod of the hydraulic rod is connected to the support member, and the hydraulic rod can control the piston rod to rise and fall to adjust the included angle between the inclined plate 120 and the horizontal plane.

[0052] In an embodiment, the housing 100 is provided with a level 190 on the side away from the inclined plate 120, the top rod 180 is a hydraulic rod, and the piston rod of the hydraulic rod is connected to the support. According to the feedback information of the level 190, the piston rod can be adjusted to make the support horizontally arranged and the inclined plate 120 fixedly arranged at an angle with the horizontal plane, so as to smoothly load and unload the culvert.

[0053] In addition, a controller can also be arranged on the housing 100, the controller is connected to the power source of the hydraulic rod, and the controller is provided with a switch button. When the button is opened by a person, the controller can receive the feedback information of the level 190, and then send an adjustment signal to the power source to synchronously adjust the height of the piston rod, so that the support is horizontal. After the adjustment is completed, the operator can close the button, so that the support is fixed relative to the vehicle during the vehicle transportation of the culvert. In the embodiment, the two top rods 180 at the bottom of the housing 100 are hydraulic rods, which are respectively controlled by two power sources to expand the adjustment range of the two piston rods. In addition, the hydraulic rod can be arranged at only one end of the bottom of the housing 100, and a top rod 180 with a fixed length is arranged at the other end of the bottom of the housing 100. The adjustment of the angle of the inclined plate 120 is realized by the length of the hydraulic rod being greater than or less than the top rod 180 with a fixed length.

[0054] Preferably, the clamping assembly includes a fixing frame 171 and a fixing screw 172. The fixing frame 171 is provided with a U-shaped groove for the fixing screw 172 to move through, so that the fixing screw 172 can be clamped to the transport vehicle for fixing the support.

[0055] In the embodiment, when the horizontal adjustment of the support is completed, the fixing frame 171 on the housing 100 is moved to be clamped to the transport vehicle. By rotating the fixing screw 172 passing through the U-shaped groove of the fixing frame 171, the fixing screw 172 is pressed against the transport vehicle, and then the two supports are fixed to the transport vehicle.

[0056] Please refer to Figure 6 Preferably, the two ends of the connecting piece 200 are respectively provided with a connecting rod 210 and a connecting groove 220. The connecting rod 210 and the connecting groove 220 of different connecting pieces 200 can be matched and connected. The limiting screw ring 230 is sleeved on the connecting piece 200 outside the side plate 140 to fix the support with the adjusted distance.

[0057] When the personnel fix the two shells 100 through the support rod, the connecting piece 200 is connected with the connecting groove 220 on the other connecting piece 200 through the connecting rod 210, and then the two connecting pieces 200 are fixedly connected, the number of the connecting pieces 200 to be fixed is connected according to the length of the culvert, the connecting piece 200 after the length is adjusted is inserted into the side plate 140 between the two shells 100, and the limiting screw ring 230 is connected with the two ends of the connecting piece 200, until the limiting screw ring 230 abuts against the side plate 140, the relative position between the two shells 100 can be adjusted according to the length of the culvert, and the culvert of different lengths can be applied.

[0058] Please refer to Figure 8 Preferably, all the inclined plates 120 include the first inclined plate 121 and the second inclined plate 122 adjacent to each other, the first inclined plate 121 forms the first gap with the shell 100, and the second inclined plate 122 forms the second gap at the end away from the first gap, so that the culvert moves to the second inclined plate 122 and the second gap after passing through the first inclined plate 121 and the first gap, and the higher end of the first inclined plate 121 is provided with the protrusion 123 to prevent the culvert from moving out of the shell 100 along the second gap after passing through the second inclined plate 122.

[0059] It can be understood that the inclined plate 120 includes the first inclined plate 121 and the second inclined plate 122 adjacent to each other, the first inclined plate 121 forms the first gap with the shell 100, and the second inclined plate 122 can form the second gap with the vertical discharging plate 150, the first gap and the second gap are arranged left and right and have different heights, so that the moving path of the culvert in the placing cavity 110 is S-shaped, the culvert can be stacked in the placing cavity 110 as much as possible while slowly falling, and the higher end of the first inclined plate 121 is provided with the protrusion 123 to prevent the culvert from moving out of the shell 100 due to large horizontal displacement when the culvert falls from the second inclined plate 122 to the first inclined plate 121.

[0060] It should be noted that the specific number of the first inclined plate 121 and the second inclined plate 122 and the included angle with the horizontal plane can be adjusted according to the actual situation, which is not limited here as long as the above purpose can be achieved.

[0061] Preferably, the side of the discharging plate 150 facing the inclined plate 120 is fixedly connected with a plurality of protruding plates 151, and all the protruding plates 151 are uniformly arranged along the extension direction of the discharging plate 150 to limit the movement of the culvert on the discharging plate 150.

[0062] When the culvert is discharged through the discharging plate 150, the potential energy of the culvert rolling downward is slowed down through the protruding plate 151 on the discharging plate 150, so that the culvert is slowly discharged, and the impact force borne by the baffle 160 when the culvert is controlled to stop discharging is reduced.

[0063] Preferably, the slope 130 is parallel to the second inclined plate 122.

[0064] In the embodiment, the inclination of the slope 130 is consistent with the inclination of the second inclined plate 122, facilitating the downward rolling of the culvert.
