Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a muck removal vehicle. Background Technology

[0002] A muck truck is a vehicle used to transfer muck materials. Existing mainstream muck trucks generally consist of a chassis with a running gear, and a cargo box connected to the chassis to hold the muck materials. The entire upper part of the cargo box is open for loading and unloading the muck materials. This type of muck truck is widely used due to its simple structure, but the following problems exist in actual use:

[0003] (1) When the muck truck travels on an inclined slope, such as inside the inclined arch foundation under excavation, the muck truck will tilt with the slope, resulting in one end of the top opening of the truck body being higher than the other, making it easy for the muck material to fall from the lower end of the opening.

[0004] (2) The existing slag trucks only have an opening at the top of the truck bed. When it is necessary to unload the slag, either an excavator is needed to remove the slag from the truck bed one shovel at a time, or a crane is needed to flip the entire slag truck so that the slag leaves the truck bed under the action of gravity. However, both methods require additional equipment and operations, which makes unloading the slag time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to overcome the technical problems of existing slag removal vehicles being time-consuming and labor-intensive to unload slag, and being prone to slag spillage when operating on inclined slopes, and to provide a slag removal vehicle.

[0006] In a first aspect, the present invention provides a slag removal vehicle, comprising: a frame, a traveling device provided at the bottom of the frame; a carriage connected to the frame; a feed inlet provided at the top of the carriage, the area of ​​the feed inlet being smaller than the area of ​​the top of the carriage, the feed inlet being located near one end of the carriage along the traveling direction of the traveling device; the height of the feed inlet near the middle of the carriage along the traveling direction of the traveling device being higher than the height of the other end of the feed inlet; and a discharge outlet provided at the bottom of the carriage, with an openable and closable cover plate provided at the discharge outlet.

[0007] The slag removal vehicle of the present invention has an inlet and an outlet at the top and bottom of the truck body, respectively, and an openable cover at the outlet. When it is necessary to load slag into the truck body, the cover is closed to close the outlet, and the slag can be poured into the truck body through the opening (inlet) at the top of the truck body, just like in the prior art, and the slag is kept inside the truck body for easy transfer. When it is necessary to unload the slag, the slag removal vehicle can be moved above the predetermined unloading position, and then the cover is opened, so that the slag can leave the truck body spontaneously from the outlet under the action of gravity, without the need to use an excavator or crane as in the prior art, thereby greatly improving the efficiency of slag unloading operations and reducing operating costs.

[0008] Meanwhile, this solution also makes the area of ​​the feed inlet smaller than the area of ​​the top of the car body, and sets the feed inlet to one end of the car body along the traveling direction of the traveling device. That is, in this solution, the top of the car body is open at one end along the traveling direction of the traveling device and closed at the other end. When the slag truck travels on an inclined slope, the slag truck is configured such that the closed end of the top of the car body is close to the bottom of the slope, and the end of the car body with the feed inlet is close to the top of the slope. This way, the closed top of the car body can be used to block the slag material, thereby preventing the slag material from spilling.

[0009] With one end of the feed inlet higher than the other, it's as if a corner of the car body has been cut off. This allows for an increase in the feed inlet area without reducing the area of ​​the enclosed portion of the car body's top surface, thus improving the efficiency of slag loading operations.

[0010] Preferably, the cover plate is sway-connected to the frame, and the axis of the sway connection is set along the traveling direction of the traveling device.

[0011] This solution recommends that the cover plate be connected to the frame by a swing connection. When the cover plate is opened, as long as the swing angle of the cover plate does not exceed 90°, the projection of the cover plate on the horizontal plane will not exceed the projection of the frame and the box on the horizontal plane. That is, the opening of the cover plate will not cause the projected area of ​​the slag discharge car on the horizontal plane to increase, which can reduce the possibility of interference with other structures when the cover plate is opened.

[0012] Preferably, it further includes a first telescopic rod, the length of which is perpendicular to the traveling direction of the traveling device, and both ends of the first telescopic rod are respectively hinged to the frame and the cover plate, with the hinge axis set along the traveling direction of the traveling device.

[0013] This solution recommends one specific structure that can drive the cover to open and close.

[0014] Preferably, the first telescopic rod is located on at least one side of the cover plate along the traveling direction of the traveling device.

[0015] This solution will reduce the encroachment of the first telescopic bar on the interior space of the carriage, which will help maintain the effective volume of the carriage.

[0016] Preferably, the cover plate is provided with a locking hole, the axis of which is set along the traveling direction of the traveling device; a locking pin is movably connected to the frame, the axis of which is set along the traveling direction of the traveling device, and the position of the locking pin along the traveling direction of the traveling device is adjustable; when the cover plate is fastened to the discharge port, the axis of the locking pin and the locking hole can be aligned, and the locking pin can be inserted into or removed from the locking hole.

[0017] This solution can lock the cover plate in the closed (i.e., latched) position by inserting the locking pin into the locking hole, thereby preventing the first telescopic rod from malfunctioning and causing the cover plate to open spontaneously under the gravity of the slag, which would lead to the slag spilling out accidentally. When the cover plate needs to be opened, the locking pin can be pulled out of the locking hole to unlock the swing freedom of the cover plate.

[0018] Preferably, a second telescopic rod is connected to the frame, and the telescopic direction of the second telescopic rod is set along the traveling direction of the traveling device; a locking pin is connected to the free end of the second telescopic rod.

[0019] This solution recommends one specific structure that can drive the locking pin to move.

[0020] Preferably, there are two cover plates, which are respectively connected to the two sides of the discharge port along the width direction of the vehicle frame.

[0021] This solution involves installing two cover plates at the discharge port, which reduces the size of a single cover plate while maintaining the same discharge port area, thereby reducing the difficulty of driving the cover plate.

[0022] Preferably, the frame is connected to a traction connection point, which includes a traction ring and / or a traction hook.

[0023] This solution allows workers to easily connect a traction rope to the frame, enabling the muck truck to move by pulling the traction rope with a winch. This facilitates external power for the muck truck, thereby reducing its structural complexity and manufacturing cost.

[0024] Preferably, the walking device includes walking wheels.

[0025] This solution provides one specific walking device.

[0026] Preferably, the traveling wheel has a flange on at least one side along its axial direction.

[0027] This design allows the wheels to move easily on the track and prevents them from separating from the track.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] This utility model provides a slag discharge vehicle. By setting an inlet and an outlet at the top and bottom of the vehicle body respectively, with the outlet area being smaller than the top area of ​​the vehicle body and one end higher than the other, and by setting an openable cover at the outlet, it is possible to prevent slag from spilling from the inlet when the slag discharge vehicle is traveling on an inclined slope, and to allow the slag to spontaneously leave the vehicle body from the outlet under the action of gravity during slag discharge. This can significantly improve the efficiency of slag discharge operations and reduce operating costs. Attached Figure Description

[0050] Example 1

[0051] like Figures 1 to 8 As shown, a slag removal vehicle includes a frame 1 and a carriage 2; a traveling device 11 is provided at the bottom of the frame 1; the carriage 2 is connected to the frame 1; a feed inlet is provided at the top of the carriage 2, the area of ​​the feed inlet is smaller than the area of ​​the top of the carriage 2, and the feed inlet is located near one end of the carriage 2 along the traveling direction of the traveling device 11; the height of the feed inlet near the middle of the carriage 2 along the traveling direction of the traveling device 11 is higher than the height of the other end of the feed inlet; a discharge outlet is provided at the bottom of the carriage 2, and an openable cover plate 3 is provided at the discharge outlet.

[0052] exist Figures 3 to 6 ,as well as Figure 7 The various directions of this embodiment are also indicated by a rectangular coordinate system, where the X-axis represents the walking direction of the walking device 11; the Z-axis represents the height direction; and the Y-axis represents the width direction of the frame 1. The Y-axis is not marked in the figure, but it is perpendicular to both the X-axis and the Z-axis.

[0053] In optional implementations, such as Figure 2 As shown, the frame 1 is a frame-shaped steel structure made of square steel splicing, with a hollow middle section, in order to facilitate the subsequent connection of the carriage 2 and maximize the discharge port area of ​​the carriage 2.

[0054] In optional embodiments, the walking device 11 includes, but is not limited to, a wheeled walking device 11, a tracked walking device 11, or a footed walking device 11.

[0055] In optional implementations, such as Figures 3 to 5 As shown, the carriage 2 has a box-like structure, but its bottom (lower end along the Z-axis) does not have an end plate, thus allowing the entire bottom of the carriage 2 to serve as a discharge port; its top (upper end along the Z-axis) only has a top sealing plate 21 on one side along the X-axis, and the length of the top sealing plate 21 along the X-axis is less than the corresponding length of the carriage 2, thus only closing a portion of the top area of ​​the carriage 2, while leaving the other portion open as a feed inlet; and a corner of the carriage 2 is cut off at the end where the feed inlet is located, thus forming a shape where the feed inlet is higher at one end and lower at the other along the X-axis, so that when the carriage 2...Figure 8 As shown, when the top sealing plate 21 is tilted due to the terrain, it can block the slag 7 and prevent the slag 7 from falling. The tilt of the inlet itself can offset part of the terrain tilt, so that the inlet is closer to the horizontal than the terrain, which makes it easier for the excavator to dump the slag 7 into it.

[0056] In optional embodiments, the opening and closing method of the cover plate 3 includes, but is not limited to, translational, swinging, or folding. For example, a slide rail, lead screw, or rack with a length arranged along the X-axis can be provided at the discharge port, and a slider can be slidably connected on the slide rail, a lead screw nut can be threadedly connected on the lead screw, or a gear can be meshed on the rack. Then, the cover plate 3 can be fixedly connected to the slider, the cover plate 3 can be fixedly connected to the lead screw nut, or the cover plate 3 can be rotatably connected to the gear.

[0057] In an optional embodiment, the cover plate 3 is sway-connected to the frame 1, and the axis of the sway connection is arranged along the traveling direction of the traveling device 11.

[0062] In the above embodiment, a limiting plate 32 is provided on the cover plate 3, the normal direction of the limiting plate 32 is arranged along the X-axis direction, and a locking hole 321 is provided in the limiting plate 32; a corresponding limiting hole is provided at the bottom of the carriage 2, so that when the cover plate 3 is fastened to the discharge port, as Figure 6 As shown, the limiting plate 32 can be inserted into the limiting hole, and then the locking pin 51 is further inserted into the locking hole 321 to lock the position of the cover plate 3.

[0063] In the above embodiment, the length of the locking hole 321 along the Z-axis is greater than its length along the Y-axis, thereby reducing the control accuracy requirements of the locking pin 51.

[0064] In the above embodiments, the movable connection between the locking pin 51 and the frame 1 can be achieved in a variety of ways. For example, a slide rail, lead screw, or rack with a length arranged along the X-axis can be provided on the frame 1, and a slider can be slidably connected on the slide rail, a lead screw nut can be threaded on the lead screw, or a gear can be meshed on the rack.

[0070] In an optional embodiment, the walking device 11 includes wheels. For example... Figure 1 As shown, at least one wheel is provided at each of the four corners of the frame 1.

[0071] In an optional embodiment, the traveling wheel has a flange on at least one side along its axial direction to facilitate stable travel of the traveling wheel on the track 6.
