DETAILED DESCRIPTION
[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0028] In the present disclosure, unless otherwise stated, directional words such as "upper", "lower", etc. are used to indicate directions or positional relationships such as Figure 4 The directions of the drawings are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.
[0029] In addition, the "width direction" can be seen Figure 4 In the width direction shown. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element and do not have order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0030] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0031] like Figures 1 to 6As shown, the first aspect of the present disclosure provides a compartment 1 for a dump truck, comprising a bucket 10, a door 20, a suspension arm 30, a rotating shaft 40, a traction member 50 and a stopper 60, wherein the door 20 is used to movably cover the side opening of the bucket 10, the door 20 is connected to a first end of the suspension arm 30, the second end of the suspension arm 30 is connected to the traction member 50, and the end of the traction member 50 away from the suspension arm 30 is connected to the vehicle frame 3, and the bucket 10 comprises a bottom plate 11 and a plurality of traction members connected above the bottom plate 11. The side plate 12 is provided, and the arm 30 is rotatably connected to the side plate 12 through a rotating shaft 40, and the rotating shaft 40 is connected between the first end and the second end of the arm 30; the car body 1 has a stationary state and a lifted state. In the stationary state, the bottom plate 11 is fitted with the frame 3 of the vehicle, and the upper end surface of the stopper 60 is abutted against the lower end surface of the arm 30. In the lifted state, the bottom plate 11 and the frame 3 have an angle, and the traction member 50 can pull the arm 30 to apply a force to the door 20 away from the bottom plate 11.
[0032] Through the above technical solution, when the above-mentioned carriage 1 is unloaded, that is, when the carriage 1 is lifted, the arm 30 connected to the carriage 1 will be driven to move upward synchronously. During the movement of the arm 30, the traction member 50 connected to the second end thereof will be driven to move, and the traction member 50 is connected to the frame 3 of the vehicle. In this way, when the arm 30 moves to a certain height, since the length of the traction member 50 is certain, the traction member 50 will apply a downward pulling force to the second end of the arm 30. At this time, the arm 30 will rotate around the rotating shaft 40 under the pulling action of the traction member 50. While the second end of the arm 30 moves downward, the first end of the arm 30 and the door 20 connected to the first end of the arm 30 move upward, thereby increasing the distance between the door 20 and the floor 11 of the vehicle, and then increasing the opening range of the door 20, so as to facilitate the unloading of larger materials, reduce or avoid the accumulation and blockage of materials during the unloading process, and improve the efficiency and safety of unloading.
[0033] It should be noted that the present disclosure does not limit the specific position of the vehicle door 20. For example, for a front-lift dump truck, the vehicle door 20 may be a rear door, and for a side-lift dump truck, the vehicle door 20 may be a side door.
[0034] In the present disclosure, the length of the above-mentioned traction member 50 should be specific, that is, when the car body 1 is in a raised state, the distance between the second end of the boom 30 and the fixing point of the traction member 50 and the frame 3 is just equal to the length of the traction member 50. It can also be understood that when the car body 1 is in a raised state, the traction member 50 is just straightened (the traction member is in a state where it cannot be stretched any further).
[0035] In addition, the car 1 also includes a stopper 60. When the car 1 is in a stationary state, the upper end surface of the stopper 60 can be pressed against the lower end surface of the arm 30. On the one hand, the stopper 60 can limit the arm 30, thereby preventing the arm 30 from swinging up and down around the rotating shaft 40 during the operation of the vehicle, thereby improving the stability of the arm 30. On the other hand, the support member can also support the arm 30 during the process of pressing against the lower end surface of the arm 30, thereby sharing the gravity of the arm 30 and the door 20 together with the rotating shaft 40, reducing the pressure on the rotating shaft 40, and further improving the service life and stability of the rotating shaft 40.
[0036] In one embodiment provided by the present disclosure, optionally, as Figure 2 , Figure 3 As shown, the stopper 60 may include a transverse support plate 61 and a longitudinal support plate 62, wherein the transverse support plate 61 extends in the width direction of the carriage 1, and the longitudinal support plate 62 extends in the up-down direction of the carriage 1, and the transverse support plate 61 is connected to the longitudinal support plate 62 and is formed into an L shape, and the longitudinal support plate 62 is connected to the side plate 12, and the upper end surface of the transverse support plate 61 is used to abut against the lower end surface of the suspension arm 30 when the carriage 1 is in a stationary state. In other words, the longitudinal support plate 62 can be fixed to the side plate 12, and the transverse support plate 61 can support the suspension arm 30, and the two do not interfere with each other, and can achieve stable support for the suspension arm 30, and the stopper 60 formed in an L shape can achieve the support function for the suspension arm 30, and also has a small volume, which can reduce the overall weight of the carriage 1.
[0037] In addition, in order to further improve the strength of the stopper 60 , the stopper 60 may further include a reinforcement member 63 , and the reinforcement member 63 is connected between the transverse support plate 61 and the longitudinal support plate 62 .
[0038] For example, in the present disclosure, the stopper 60 may also be made directly of angle steel, which has the advantages of being inexpensive and easily available, and has high strength, can meet pressure requirements, and can reduce modification costs.
[0039] In addition, the present disclosure does not limit the specific connection method between the above-mentioned stop member 60 and the side panel 12. For example, the stop member 60 can be connected to the side panel 12 in a detachable manner, such as a fastener, or can be connected in a non-detachable manner such as welding, riveting, etc.
[0040] Alternatively, in another embodiment provided by the present disclosure, the above-mentioned stop member 60 can be a bolt, and a screw hole is formed on the side wall. The bolt is partially threaded in the screw hole, and the part of the bolt protruding from the side wall is used to resist the boom 30. In short, as long as the supporting effect on the boom 30 can be achieved, the present disclosure does not limit the specific structure and supporting method of the stop member 60.
[0041] Alternatively, if Figure 3 As shown, there are two hanging arms 30, and a hinge shaft 31 is formed on one side of each hanging arm 30 close to the door 20, and hinge holes are formed on the upper ends of both sides of the door 20. Each hinge shaft 31 can be rotatably connected in the corresponding hinge hole, and the door 20 is hinged to the hanging arm 30. The two hanging arms 30 support the door 20 from both sides of the door 20, thereby improving the stability of the door 20 during the opening and closing process. In addition, since the door 20 and the hanging arm 30 are hingedly connected, when the car body 1 is lifted, the door 20 can automatically droop under the action of gravity, thereby reducing the amplitude of the door 20 extending outward, thereby reducing the space required for unloading, so as to avoid interference and collision between the door 20 and foreign objects during the unloading process.
[0042] Alternatively, the first end of the suspension arm 30 may be connected to the vehicle door 20 by welding, so as to avoid the problem that the vehicle door 20 sags due to its own gravity during the lifting process and affects its own opening degree.
[0043] Alternatively, if Figure 2 , Figure 3 As shown, the carriage 1 may further include a resisting member 70, which is connected to the edge of the door 20, and is arranged protruding from the door 20 along the width direction of the carriage 1. The end surface of the first end of the suspension arm 30 is used to resist against the resisting surface 71 of the resisting member 70 when the carriage 1 is in the lifting state. By providing the resisting member 70, the suspension arm 30 can resist against the resisting surface 71 when the carriage 1 is in the lifting state, and the resisting member 70 is connected to the door 20, thereby realizing the resisting of the door 20, so that the door 20 can have a larger opening, which further facilitates the sliding of materials.
[0044] Optionally, in an exemplary embodiment provided by the present disclosure, as Figure 2 , Figure 3As shown, the first end of the suspension arm 30 is formed with a top-butting inclined surface 32 for abutting against the top-butting surface 71. The top-butting inclined surface 32 is arranged opposite to the top-butting surface, and the inclination angle of the top-butting inclined surface 32 is the same as the inclination angle of the top-butting surface. In this way, during the lifting process of the car body 1, under the pulling of the traction member 50, the first end of the suspension arm 30 gradually rises and drives the door 20 to rise synchronously. At the same time, the top-butting inclined surface 32 of the suspension arm 30 abuts against the top-butting surface 71 of the abutting member 70, thereby preventing the door 20 from sagging under the action of gravity, thereby achieving the purpose of further increasing the opening of the door 20.
[0045] Alternatively, if Figure 4 , Figure 6 As shown, the carriage 1 further includes a reinforcing plate 80 and a connecting assembly 90. The first end of the reinforcing plate 80 is welded to the frame 3. The second end of the reinforcing plate 80 extends in a direction away from the frame 3 along the width direction of the carriage 1. The connecting assembly 90 is connected to the second end of the reinforcing plate 80. The end of the traction member 50 away from the boom 30 is connected to the connecting assembly 90. By providing the reinforcing plate 80, the contact area between the frame 3 and the traction member 50 can be increased, thereby reducing the local stress applied to the frame 3 during the process of the traction member 50 pulling the boom 30. In addition, the provision of the reinforcing plate 80 can also avoid direct contact between the traction rope and the frame 3, thereby avoiding the problem of affecting the overall strength of the frame 3 due to changes (such as opening holes) in the frame 3.
[0046] Alternatively, if Figure 4 , Figure 6 As shown, the connection assembly 90 may include a connection shaft 91, a locking pin 92, and two supporting ears 93 arranged opposite to each other. The two supporting ears 93 are connected to the second end of the reinforcing plate 80. A mounting hole 931 is formed on each supporting ear 93. The connection shaft 91 is detachably inserted into the two mounting holes 931. An insertion hole is formed at the end of the connection shaft 91. The locking pin 92 is detachably inserted into the insertion hole to limit the movement of the connection shaft 91 in the mounting hole 931. The end of the traction member 50 away from the boom 30 is connected to the connection shaft 91. In this way, one end of the traction member 50 can be directly connected to the connection shaft 91 by fasteners or sleeves, and the two supporting ears 93 can provide stable support for the connection shaft 91, thereby improving the stability of the connection shaft 91. Furthermore, since the connecting shaft 91 can be connected to the two supporting ears 93 in a detachable manner, when the traction member 50 needs to be connected, the locking pin 92 can be pulled out from the plug hole of the connecting shaft 91 first. At this time, the connecting shaft 91 can move in the mounting hole 931, thereby achieving the connection shaft 91 being disengaged from the mounting hole 931, and then the end of the traction rope away from the boom 30 is hung on the connecting shaft 91, and the connecting shaft 91 is re-inserted into the mounting hole 931, and the connecting shaft 91 is fixed by the locking pin 92. The disassembly is simple and convenient for the operator to operate.
[0047] Optionally, in an exemplary embodiment provided by the present disclosure, as Figure 4 , Figure 5 As shown, the rotating shaft 40 may include a head 41, a smooth section 42 and a threaded section 43, the smooth section 42 is connected between the head 41 and the threaded section 43, a through hole penetrating the thickness of the arm 30 is formed, a threaded hole is formed on the side plate 12, the smooth section 42 is rotatably inserted into the through hole, and the threaded section 43 is threadedly connected to the threaded hole. The smooth section 42 has a small friction force, so that the rotation of the arm 30 inserted on the smooth section 42 is facilitated, and the rotating shaft 40 is connected to the side plate 12 in the above-mentioned detachable manner, which is also more convenient for the maintenance and replacement of the rotating shaft 40 in the later stage.
[0048] Alternatively, if Figure 1 As shown, the truck bed 10 may further include a front plate 13, which is connected between the two side plates 12, and is inclined from top to bottom in a direction away from the cab. In other words, the lower end of the front plate 13 is inclined backward, so that under the condition of minimizing the capacity of the vehicle compartment 1, a space for installing the oil cylinder can be provided below the front plate 13.
[0049] In an exemplary embodiment provided by the present disclosure, the angle between the front plate 13 and the bottom plate 11 is 60° to 70°.
[0050] In addition, the present disclosure does not limit the specific material and type of the traction member 50. Figure 1 , Figure 4 As shown, the traction member 50 may be a chain, which has high strength and can meet the strength requirement in the process of pulling the boom 30, and for the embodiment in which the connecting assembly 90 includes a connecting shaft 91, the chain ring of the chain may be directly sleeved on the connecting shaft 91. Alternatively, the traction member 50 may also be a steel wire rope.
[0051] The second aspect of the present disclosure provides a vehicle, comprising a frame 3 and the above-mentioned carriage 1, wherein the carriage 1 is mounted on the frame 3. The vehicle has all the beneficial effects of the above-mentioned carriage 1, which will not be described in the present disclosure.
[0052] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0054] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
