Description

Technical Field

[0001] The present invention relates to the field of transportation of metal raw materials, and particularly to transportation equipment for basic metal materials. Background Art

[0002] Using a dump freight vehicle to implement point-to-point transfer of metal raw materials is a common material transportation method in mining areas. Considering rigid indicators such as environmental protection, a covering object must be installed above the dump truck hopper to cover the materials. Currently, the methods of installing a covering part above the hopper can be subdivided into two types. One is to manually cover the canvas above the hopper, and the other is to configure a complete set of automatic tarpaulin systems.

[0003] The transportation activities of raw materials in mining areas attach great importance to efficiency, that is, the dump trucks line up in sequence to wait for loading and unloading. Accordingly, it is obvious that the driver and crew getting out of the vehicle to fiddle with the canvas after loading and unloading will consume time, resulting in an extended detention time of the vehicles at the rear and affecting the transportation efficiency.

[0004] The automatic tarpaulin system can improve the above problems. However, the extension or retraction of the tarpaulin can only be in a single direction. Therefore, when the materials in the hopper protrude outward relative to the hopper, the materials at the protruding part will be pushed by the tarpaulin and leak out of the hopper. In addition, considering the actual use of the driver and crew, the extension or retraction time of the automatic tarpaulin system is mostly more than 10 seconds each time. Considering the overall cost of the automatic tarpaulin system, the cost performance of using this system is not high. Accordingly, a transportation equipment for basic metal materials with high covering efficiency and good covering effect is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide transportation equipment for basic metal materials to solve the above technical problems.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions to achieve:

[0007] Transportation equipment for basic metal materials, including a vehicle and a hopper installed at the vehicle shelf and capable of flipping relative to the vehicle. A swing rod control member is arranged along the length direction of the hopper top. The swing rod control member includes a support pipe fixed to the hopper top and a plug rod movably inserted into the support pipe;

[0008] A plurality of pipe grooves are arranged along the length direction of the support pipe. A rod groove is opened on the side wall of the plug rod, which is in the same direction as the notch direction of the pipe groove and is exposed outward from the pipe groove. A swing rod passing through the pipe groove and extending outward is arranged with the rod groove as a transfer point. Among them, a canvas is arranged between adjacent swing rods;

[0009] A first spring is arranged in the width direction of the pipe groove, and both ends of the first spring are fixed to the side wall of the swing rod and the notch of the pipe groove respectively;

[0010] A rope is arranged at the front of the vehicle. The rope extends into the support tube and is connected to one end of the insertion rod. When the vehicle bed rotates upward relative to the vehicle, the rope is used to make multiple swing rods rotate and fold back to one side of the support tube.

[0011] Preferably, a fixing member facing the port of the support tube is arranged in the width direction of the top of the vehicle bed. The rope passes through the fixing member and extends into the support tube and is connected to one end of the insertion rod. When the vehicle bed rotates downward relative to the vehicle, the fixing member is used to limit the movement of the insertion rod in the support tube.

[0012] Preferably, the fixing member is an electromagnetic fixing member, and the insertion rod is a metal rod body magnetically adapted to the electromagnetic fixing member.

[0013] Preferably, the fixing member includes a support and an insertion rod docking rod connected to one end of the insertion rod. The support is fixed at the top of the vehicle bed and faces the port of the support tube. A groove is formed in the side wall of the insertion rod docking rod, and a movable block is rotatably connected in the groove. A second spring with ends respectively fixed to the movable block and the bottom of the groove is arranged between the movable block and the bottom of the groove. When the insertion rod docking rod passes through the support and the groove is exposed, the insertion rod docking rod extends outward relative to the groove and abuts against the support.

[0014] Preferably, the unfolding angle between the insertion rod docking rod and the groove faces the support.

[0015] Preferably, the groove length of the tube groove is greater than the groove length of the rod groove.

[0016] Preferably, a guide groove is arranged on the inner wall of the support tube, and a ball extending into the guide groove and slidingly matched with the guide groove is arranged on the side wall of the insertion rod. When the rope pulls the insertion rod to move, the insertion rod rotates in the support tube.

[0017] Preferably, when the rope pulls the insertion rod to move, the insertion rod rotates upward relative to the support tube.

[0018] Preferably, the rope is elastic.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. By intercepting the pulling force generated when the vehicle bed rotates relative to the vehicle, the swing rods installed at the swing rod control member can fold back to one side of the swing rod control member, and when the swing rods need to be extended outward, they can quickly reset above the vehicle bed, and a canvas is used to cover the vehicle bed.

[0021] 2. A guide groove is arranged on the inner wall of the support tube, and the guide groove is slidingly matched with the ball at the insertion rod. When the rope is used to pull the insertion rod, the insertion rod rotates upward in the support tube, and after the insertion rod is reset, when the canvas is unfolded, it can cover the top of the pile in a covering manner from top to bottom.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0036] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0037] Embodiment 1

[0038] In this embodiment, a transportation device for metal base materials is proposed, including a vehicle 1 and a hopper 8 installed at the shelf of the vehicle 1. Among them, the hopper 8 is rotatably connected to the vehicle 1, and the hopper 8 is supported by a hydraulic system (not marked in the figure). Accordingly, by controlling the pumping in or pumping out of the hydraulic fluid of the hydraulic system, the specific range from the hopper 8 to the vehicle 1 is adjusted. For example Figure 2 in, the hopper 8 is turned upwards relative to the vehicle 1;

[0039] Please refer to Figure 1 , a swing rod control member 7 is arranged along the length direction of the top of the hopper 8;

[0040] Please refer to Figures 6 - 10 , the swing rod control member 7 includes a support pipe 74 fixed to the top of the hopper and a plug rod 72 movably inserted into the support pipe 74. It should be noted that the plug rod 72 and the support pipe 74 are almost seamless, so there is no clearance between the plug rod 72 and the support pipe 74.

[0041] Please refer to Figure 6 , a plurality of pipe grooves 73 are arranged along the length direction of the support pipe 74. A rod groove 71 is opened on the side wall of the plug rod 72 in the same direction as the notch direction of the pipe groove 73 and exposed outward from the pipe groove 73. Among them, the rod groove 71 is not only a slot for the swing rod 6, but also a rotation groove for the swing rod 6, that is, with the rod groove 71 as the transfer point, the swing rod 6 passes through the pipe groove 73 and extends outward.

[0042] Of course, in order to cover the materials in the hopper 8, a canvas 5 is arranged between adjacent swing rods 6. In addition, please refer to Figures 1 - 5 , at the outermost swing rod 6, not only a canvas 5 is arranged from it to the adjacent swing rod 6, but also a canvas 5 independently connected to the swing rod 6 is arranged on the other side facing away from the canvas 5. This canvas 5 can cover the vacant positions that are difficult to cover by the canvas 5 at the adjacent swing rod 6.

[0043] Please refer to Figures 7 - 9 , a first spring 4 is arranged in the width direction of the pipe groove 73, and both ends of the first spring 4 are fixed to the side wall of the swing rod 6 and the notch of the pipe groove 73 respectively.

[0044] A rope 2 is provided at the front of the vehicle 1. The rope 2 extends into the support tube 74 and is connected to one end of the insertion rod 72. When the cargo bed 8 rotates upward relative to the vehicle 1, it causes a plurality of swing rods 6 to rotate and fold back to one side of the support tube 74.

[0045] Combined with the above description, in the embodiment, the metal base material transportation equipment combines components such as the vehicle 1, the rope 2, the first spring 4, the canvas 5, the swing rod 6, the rod groove 71, the insertion rod 72, the tube groove 73, the support tube 74, and the cargo bed 8. The purpose is to control the relative position of the canvas 5 to the cargo bed 8 during the upward or downward rotation of the cargo bed 8 relative to the vehicle 1. The following will be described with specific examples:

[0046] Example 1: When loading is required, the cargo bed 8 is supported by the hydraulic system, causing the cargo bed 8 to rotate upward relative to the vehicle 1. During this period, the position of the front of the vehicle 1 remains unchanged. Accordingly, the rope 2 pulls the insertion rod 72 in the support tube 74, and promotes the swing rod 6 rotatably connected to the insertion rod 72 to deflect relative to the insertion rod 72 when contacting the wall of the tube groove 73 (when the first spring 4 is under the action of the torsional force, it will also give the swing rod 6 the required torsional force for deflection relative to the insertion rod 72), and causes the swing rod 6 to deflect to one side of the support tube 74, revealing the space inside the cargo bed 8 for loading operations. After loading is completed and the cargo bed 8 slowly descends (the pulling force of the rope 2 decreases and gradually disappears), the first spring 4 releases the pressure acting on the first spring 4 during the deflection of the insertion rod 72, causing the insertion rod 72 to reset, extending the plurality of swing rods 6 to the outside of one side of the support tube 74, and covering the cargo bed 8 with the canvas 5.

[0047] Embodiment 2

[0048] In this embodiment, a metal base material transportation equipment is proposed, including the vehicle 1 and the cargo bed 8 installed on the shelf of the vehicle 1. Among them, the cargo bed 8 is rotatably connected to the vehicle 1, and the cargo bed 8 is supported by a hydraulic system (not marked in the figure). Accordingly, by controlling the pumping in or pumping out of the hydraulic fluid of the hydraulic system, the specific range of the cargo bed 8 to the vehicle 1 is adjusted. For example Figure 2 in which the cargo bed 8 rotates upward relative to the vehicle 1;

[0049] Please refer to Figure 1 , arrange the swing rod control member 7 along the length direction of the top of the cargo bed 8;

[0050] Please refer to Figures 6 - 10 , the swing rod control member 7 includes a support tube 74 fixed to the top of the cargo bed and an insertion rod 72 movably inserted into the support tube 74. It should be noted that the insertion rod 72 and the support tube 74 are almost seamless, so there is no clearance between the insertion rod 72 and the support tube 74.

[0051] Please refer to Figure 6, a plurality of pipe grooves 73 are arranged along the length direction of the supporting pipe 74, and a rod groove 71 which is consistent with the notch direction of the pipe groove 73 and is exposed outward from the pipe groove 73 is formed on the side wall of the insertion rod 72. Among them, the rod groove 71 is not only the insertion slot of the swing rod 6, but also the rotation groove of the swing rod 6, that is, taking the rod groove 71 as the transfer point, the swing rod 6 passes through the pipe groove 73 and extends outward.

[0052] Of course, in order to cover the materials in the cargo box 8, a canvas 5 is arranged between adjacent swing rods 6. In addition, please refer to Figures 1 - 5 , at the outermost swing rod 6, not only a canvas 5 is arranged from the outermost swing rod 6 to the adjacent swing rod 6, but also a canvas 5 independently connected to the swing rod 6 is arranged on the other side facing away from the canvas 5. The canvas 5 can cover the vacant position that is difficult to be covered by the canvas 5 at the adjacent swing rod 6.

[0053] Please refer to Figures 7 - 9 , a first spring 4 is arranged in the width direction of the pipe groove 73, and both ends of the first spring 4 are fixed to the side wall of the swing rod 6 and the notch of the pipe groove 73 respectively.

[0054] Different from Embodiment 1, in this embodiment, a fixing member 3 facing the port of the supporting pipe 74 is arranged in the width direction of the top of the cargo box 8. Among them, the rope 2 passes through the fixing member 3 and extends into the supporting pipe 74 and is connected to one end of the insertion rod 72. When the cargo box 8 rotates downward relative to the vehicle 1, the fixing member 3 restricts the movement of the insertion rod 72 into the supporting pipe 74. It should be noted that, please refer to Figure 8 and Figure 9 , in this embodiment, the fixing member 3 is an electromagnetic fixing member, and the insertion rod 72 is a metal rod body magnetically adapted to the electromagnetic fixing member.

[0055] Combined with the above description, in this embodiment, the metal base material transportation equipment combines components such as the vehicle 1, the rope 2, the electromagnetic fixing member, the first spring 4, the canvas 5, the swing rod 6, the rod groove 71, the insertion rod 72, the pipe groove 73, the supporting pipe 74 and the cargo box 8. The purpose is that when the cargo box 8 moves upward relative to the vehicle 1, the swing rod 6 deflects to one side of the supporting pipe 74, and the electromagnetic fixing member magnetically attracts the insertion rod 72 to restrict the movement of the insertion rod 72 into the supporting pipe 74, so that even when the cargo box 8 slowly falls, the swing rod 6 still deflects to one side of the supporting pipe 74 and exposes the space in the cargo box 8. Hereinafter, specific examples will be combined for description:

[0056] Example 1: When loading is required, the hydraulic system supports the hopper 8, causing the hopper 8 to flip upward relative to the vehicle 1. During this period, the position of the front of the vehicle 1 remains unchanged. Accordingly, the rope 2 pulls the inner rod 72 of the support tube 74, and prompts the swing rod 6 rotatably connected to the rod 72 to deflect relative to the rod 72 in the groove wall of the contact tube groove 73 (when the first spring 4 is under torsional force, it will also give the swing rod 6 the torsion required to deflect relative to the rod 72), thereby revealing the space inside the hopper 8. Subsequently, the hopper 8 is slowly lowered. At this time, the control of resetting the rod 72 is handed over to the driver and passengers, that is, the driver and passengers control the relative position of the rod 72 in the support tube 74 by controlling the opening or closing of the electromagnetic fixing member. Accordingly, loading can be carried out when the hopper 8 is in a horizontal state, and after loading is completed, by eliminating the magnetic attraction relationship between the electromagnetic fixing member and the rod 72, the rod 72 is quickly reset, and the canvas 5 is covered on the hopper 8.

[0057] Embodiment 3

[0058] Different from Embodiment 2, please refer to Figure 11 and Figure 12 In this embodiment, the fixing member 3 includes a support 31 and a rod docking rod 33 connected to one end of the rod 72. Among them, the support 31 is fixed at the top of the hopper 8 and is directly opposite to the port of the support tube 74. A groove is provided on the side wall of the rod docking rod 33, and a movable block 32 is rotatably connected in the groove. A second spring 34 with ends respectively fixed to the movable block 32 and the bottom of the groove is provided between the movable block 32 and the bottom of the groove, so that when the rod docking rod 33 passes through the support 31 and the groove is exposed, the rod docking rod 33 extends outward relative to the groove and abuts against the support 31.

[0059] It should be noted that the expansion angle between the rod docking rod 33 and the groove is directly opposite to the support 31.

[0060] Combined with the above description, in the embodiment, the metal base material transportation equipment combines components such as the vehicle 1, the rope 2, the support 31, the movable block 32, the rod docking rod 33, the second spring 34, the first spring 4, the canvas 5, the swing rod 6, the rod groove 71, the rod 72, the tube groove 73, the support tube 74, and the hopper 8. The purpose is that when the hopper 8 moves upward relative to the vehicle 1, the rope 2 pulls the rod 72, so that the rod docking rod 33 fixed to one end of the rod 72 extends outward relative to the support 31. During the extension, the groove is exposed, and the movable block 32 in the groove extends outward under the push of the second spring 34 and abuts against the support 31, thereby restricting the movement of the rod 72 in the support tube 74. It should be noted that the elastic force of the second spring 34 is slightly greater than the sum of the elastic forces of the multiple first springs 4, so that even when the hopper 8 is slowly falling, the swing rod 6 still deflects to one side of the support tube 74 and reveals the space inside the hopper 8. The following is an explanation with specific examples:

[0061] Example 1: When loading is required, the hydraulic system supports the dump truck body 8, causing the dump truck body 8 to flip upward relative to the vehicle 1. During this period, the position of the front of the vehicle 1 remains unchanged. Accordingly, the inner rod 72 of the support pipe 74 is pulled by the rope 2, and the swing rod 6 rotatably connected to the rod 72 is urged to deflect relative to the rod 72 in the groove wall of the contact pipe groove 73 (when the first spring 4 is under torsional force, it will also impart the torque required for the swing rod 6 to deflect relative to the rod 72), thereby revealing the space inside the dump truck body 8. Subsequently, the dump truck body 8 is slowly lowered. At this time, the control right for resetting the rod 72 is handed over to the driver and passengers, that is, the driver and passengers apply a certain force to the docking rod 33 of the rod, causing the movable block 32 to retract into the groove, so that under the joint pulling of multiple first springs 4, the rod 72 is reset. Accordingly, loading can be carried out when the dump truck body 8 is in a horizontal state. And after loading is completed, by eliminating the magnetic attraction relationship between the electromagnetic fixing member and the rod 72, the rod 72 is quickly reset, and the canvas 5 is covered over the dump truck body 8.

[0062] Embodiment 3 is an alternative embodiment of Embodiment 2. That is, the electromagnetic fixing member used in Embodiment 2 will increase the overall cost. Therefore, using the mechanical control method adopted in Embodiment 3 can reduce the overall cost and can also achieve the corresponding usage effect.

[0063] Embodiment 4

[0064] The specifications of the dump trucks in the mining area are not consistent. Accordingly, the amount of loading of the dump truck depends on the work experience of the loading personnel. Therefore, during loading, it is very common for the top of the material pile to exceed the dump truck body 8. For this reason, it is very necessary for the canvas 5 to cover the top of the pile in a covering manner from top to bottom at the moment of unfolding. Therefore, please refer to Figure 7 ..., a guide groove 75 is provided on the inner wall of the support pipe 74, and a ball 76 extending into the guide groove 75 and slidably engaged with the guide groove 75 is provided on the side wall of the rod 72, which is used to rotate the rod 72 into the support pipe 74 when the rope 2 pulls the rod 72 to move. It should be noted that when the rope 2 pulls the rod 72 to move, the rod 72 rotates upward relative to the support pipe 74.

[0065] In the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.
