Description

Technical Field

[0001] The present invention relates to the technical field of carrier vehicles, and mainly relates to a carrier vehicle capable of automatically discharging materials. Background Art

[0002] A carrier vehicle is a transportation device for transporting various materials, and various specifications can be set according to the shape, size, etc. of the transported materials. Generally speaking, the carrier vehicle used to transport large workpieces such as bridge steel structures generally has a relatively large size. After it is transported to the designated location, there are certain problems during its unloading. Since the size and weight of the transported large workpiece are relatively large, generally, equipment such as a forklift or a crane is required to lift the workpiece of the carrier vehicle for unloading. To ensure the safety and stability during the lifting of the large workpiece, the equipment such as a forklift or a crane generally inserts or buckles under the bottom of the workpiece for lifting. However, since the workpiece is directly placed on the body of the carrier vehicle and the bottom of the workpiece is closely attached to the body of the carrier vehicle, the operation of lifting the workpiece is very inconvenient. In addition, for workpieces such as sheet metal or steel bars that can be directly unloaded from the side of the carrier vehicle body, the unloading is also very inconvenient. The unloading process is generally to lift one side of the carrier vehicle body to a certain height so that the workpiece directly falls from the other side. This not only raises a large amount of dust, is prone to popping out stones when the workpiece falls, has a relatively high safety risk, but also easily causes some workpieces to have minor deformations when they are dropped, affecting their use. At the same time, since the maintenance of the carrier vehicle is relatively inconvenient, the frequent lifting of the carrier vehicle body also causes damage to itself and affects its service life. Summary of the Invention

[0003] The present invention provides a carrier vehicle capable of automatically discharging materials to solve the technical problem of inconvenient unloading of the existing carrier vehicle proposed in the above background art.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A carrier vehicle capable of automatically discharging materials includes a carrier vehicle head and a carrier vehicle body, and load-bearing tires installed under the carrier vehicle head and the carrier vehicle body; it further includes an ejection mechanism, a first ejection element, and a transition plate. The transition plate is inclined and detachably installed on the left side wall or the right side wall of the carrier vehicle body; a plurality of first weight-reducing holes and second weight-reducing holes are correspondingly opened in the middle of the top surface of the carrier vehicle body at intervals along its length direction. The first ejection element includes a plurality of elements and is correspondingly arranged below the first weight-reducing holes; a plurality of second weight-reducing grooves are correspondingly opened on the left and right sides of the top surface of the carrier vehicle body at intervals along its length direction. The ejection mechanism includes a plurality of elements and is detachably installed in the second weight-reducing grooves.

[0005] Preferably, the ejection mechanism includes a second ejection element detachably installed at the bottom of the second weight reduction groove. An installation plate is correspondingly installed at the top of the second ejection element, and a plurality of rotatable rubber rollers are evenly arranged at the top of the installation plate.

[0006] Preferably, sliding rails are correspondingly arranged on both side walls of the carrier vehicle body. A clamping strip is correspondingly arranged on one side of the transition plate, and a sliding groove is correspondingly arranged on the clamping strip. The transition plate is slidably clamped on the sliding rail on one side of the carrier vehicle body through the sliding groove.

[0007] Preferably, a support strip plate extends from the bottom of the transition plate towards the carrier vehicle body. The transition plate is inclined, and the support strip plate at its bottom is in contact with the ground.

[0008] Preferably, a convex edge extends inwards around the bottom end of the first weight reduction hole. A top plate can be correspondingly placed on the top of the convex edge, and the first ejection element is correspondingly located at the middle position below the top plate.

[0009] Preferably, a plurality of first weight reduction grooves are correspondingly formed on the front and rear sides of the top surface of the carrier vehicle body for placing the first ejection element.

[0010] Preferably, the load-bearing tires are press-fitted tires, and the first ejection element can be a jack.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In the present invention, a plurality of first weight reduction holes, second weight reduction holes, first weight reduction grooves and second weight reduction grooves are correspondingly arranged on the carrier vehicle body. For large workpieces such as transporting bridge steel structures that need to be lifted and unloaded, according to the length dimension of the workpiece, a first ejection element can be arranged at the bottom of the corresponding first weight reduction hole. The large workpiece is lifted by the first ejection element, so that the bottom of the workpiece is separated from the top surface of the carrier vehicle body, so that equipment such as a forklift or a crane can be inserted or buckled at the bottom of the workpiece for lifting, ensuring the safety and stability of its lifting. Its overall use is very flexible. The number and position of the first ejection elements can be changed according to the actual situation of the workpiece, and the first ejection elements can also be correspondingly placed in the first weight reduction grooves and move with the vehicle. Its operation is relatively convenient. Moreover, a top plate can be placed on the convex edge at the bottom end of the first weight reduction hole. The first ejection element is used to lift the top plate, and the workpiece is lifted by the top plate, so as to avoid excessive force on the ejection point when directly using the first ejection element to lift the workpiece and causing damage to the workpiece.

[0013] On the left and right sides of the top surface of the carrier vehicle body, a plurality of second weight reduction grooves are correspondingly provided. For workpieces such as transport plates or steel bars that can be directly unloaded from the side of the carrier vehicle body, the ejecting mechanism can be set in the corresponding second weight reduction groove according to the length dimension of the workpiece. By optimizing the specific structure of the ejecting mechanism, the second ejecting element is used to eject the mounting plate from the second weight reduction groove, controlling the height difference of the mounting plates ejected on the left and right sides of the carrier vehicle body. The rubber rollers on the top of the mounting plate are used to make the workpiece slide towards one side of the carrier vehicle body, and the workpiece slides to the ground through the transition plate on one side of the carrier vehicle body to complete automatic unloading. This can not only effectively avoid the ejection of stones when the workpiece falls, reduce safety risks and dust, but also avoid the generation of minor deformations when the workpiece hits. At the same time, the carrier vehicle body does not need to be lifted during the unloading process, reducing the subsequent maintenance cost and extending its service life. And the transition plate can be installed on the left or right side of the carrier vehicle body according to the actual unloading situation, and its installation is relatively convenient. The unloading directions on both sides are not limited, and its use is very flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1-6 , a carrier vehicle capable of automatic unloading in this embodiment includes a carrier vehicle head 1 and a carrier vehicle body 2, and load-bearing tires 3 installed below the carrier vehicle head 1 and the carrier vehicle body 2. The carrier vehicle further includes an ejection mechanism 5, a first ejection element 6, and a transition plate 7. The transition plate 7 is inclined and detachably installed on the left or right side wall of the carrier vehicle body 2. A plurality of first weight-reducing holes 201 and second weight-reducing holes 202 are correspondingly formed in the middle of the top surface of the carrier vehicle body 2 at intervals along its length direction. A plurality of the first ejection elements 6 are correspondingly arranged below the first weight-reducing holes 201; a plurality of second weight-reducing grooves 204 are correspondingly formed in the left and right sides of the top surface of the carrier vehicle body 2 at intervals along its length direction. A plurality of the ejection mechanisms 5 are detachably installed in the second weight-reducing grooves 204.

[0024] A plurality of first weight-reducing grooves 203 are also correspondingly formed in the front and rear sides of the top surface of the carrier vehicle body 2 for placing the first ejection elements 6. Specifically, a plurality of second weight-reducing grooves 204 are correspondingly formed in the left and right sides of the top surface of the carrier vehicle body 2 at intervals along its length direction. A plurality of first weight-reducing holes 201 are correspondingly formed in the middle of the top surface of the carrier vehicle body 2 at intervals along its length direction. Two second weight-reducing holes 202 are correspondingly provided on one side of the top surface of the carrier vehicle body 2 close to the carrier vehicle head 1. Two first weight-reducing grooves 203 are correspondingly provided between the two first weight-reducing holes 201 on one side of the top surface of the carrier vehicle body 2 close to the carrier vehicle head 1; two second weight-reducing holes 202 are also correspondingly provided on the other side of the top surface of the carrier vehicle body 2 far from the carrier vehicle head 1. Two first weight-reducing holes 201 are provided on the side of these two second weight-reducing holes 202 far from the carrier vehicle head 1, and two first weight-reducing grooves 203 are correspondingly provided between these two second weight-reducing holes 202. By correspondingly arranging a plurality of first weight-reducing holes 201, second weight-reducing holes 202, first weight-reducing grooves 203, and second weight-reducing grooves 204 on the carrier vehicle body 2 and optimizing the design of their specific structural distribution, on the one hand, the strength of the carrier vehicle body 2 can be effectively guaranteed on the premise of reducing the burden of the carrier vehicle body 2, and on the other hand, it is also convenient for the installation of vehicle body self-driving components such as the load-bearing tires 3.

[0025] The first ejection element 6 can be a jack or a cylinder or other equipment element capable of lifting. The number and position of the first ejection element 6 are determined according to the actual situation of the workpiece. For large workpieces such as transport bridge steel structures that need to be lifted and unloaded, the first ejection element 6 can be set at the bottom of the corresponding first weight-reducing hole 201 according to the actual situation of the length and size of the workpiece. The large workpiece is lifted up by the first ejection element 6 so that the bottom of the workpiece is separated from the top surface of the vehicle body 2, so that equipment such as forklifts or cranes can be inserted or buckled at the bottom of the workpiece for lifting, ensuring the safety and stability of its lifting. The number and position of the first ejection element 6 can be changed according to the actual situation of the workpiece. The first ejection element 6 can also be placed in the first weight-reducing groove 203 and moved with the vehicle. Its overall use is very flexible and convenient. The bottom of the first weight-reducing hole 201 is extended inward to form a convex edge 2011. The top of the convex edge 2011 can be correspondingly provided with an ejection plate 4. The first ejection element 6 is correspondingly located at the middle position below the ejection plate 4. A groove is correspondingly provided at the middle of the bottom end of the ejector plate 4 so that the first ejector element 6 can be correspondingly lifted in the groove. The present invention sets an ejector plate 4 in the first weight-reducing hole 201, and uses the first ejector element 6 to lift the ejector plate 4, and lifts the workpiece through the ejector plate 4, thereby avoiding damage to the workpiece caused by excessive force on the ejection point when the first ejector element 6 is directly used to lift the workpiece.

[0026] The ejection mechanism 5 includes a second ejection element 501, which is detachably installed at the bottom of the second weight reduction groove 204. A mounting plate 502 is correspondingly installed at the top of the second ejection element 501. The shape and size of the mounting plate 502 match those of the second weight reduction groove 204. A plurality of rotatable rubber rollers 503 are evenly arranged on the top of the mounting plate 502. A plurality of mounting grooves are evenly formed on the top of the mounting plate 502, and rotating shafts are correspondingly arranged in the mounting grooves. The rubber rollers 503 are rotatably installed on the rotating shafts. The second ejection element 501 can adopt equipment elements such as a jack or a cylinder that can perform jacking. The number and position of the second ejection elements 501 are determined according to the actual situation of the workpiece. For workpieces such as transport plates or steel bars that can be directly unloaded from the side of the carrier vehicle body 2, the ejection mechanism 5 can be set in the corresponding second weight reduction groove 204 according to the actual situation such as the length dimension of the workpiece. By optimizing the design of the specific structure of the ejection mechanism 5, the mounting plate 502 is ejected from the second weight reduction groove 204 by the second ejection element 501, and the height difference is formed between the mounting plates 502 ejected on the left and right sides of the carrier vehicle body 2. The rubber rollers 503 rolling on the top of the mounting plate 502 make the workpiece slide towards one side of the carrier vehicle body 2, and the workpiece slides to the ground through the transition plate 7 on this side of the carrier vehicle body 2 to complete automatic unloading. This can not only effectively prevent stones from popping out when the workpiece falls, reduce safety risks, reduce dust, but also avoid micro-deformation of the workpiece when it hits, and at the same time, the carrier vehicle body 2 does not need to be lifted during the unloading process, reducing its subsequent maintenance cost and extending its service life.

[0027] Sliding rails 205 are correspondingly arranged on the side walls of both sides of the carrier vehicle body 2. A clamping strip 701 is correspondingly arranged on one side of the transition plate 7, and a sliding groove 7011 is correspondingly arranged on the clamping strip 701. The transition plate 7 is slidably clamped on the sliding rail 205 on one side of the carrier vehicle body 2 through the sliding groove 7011. A stop block 206 is correspondingly arranged on the side of the sliding rail 205 close to the carrier vehicle head 1 to block the transition plate 7. When installing the transition plate 7, one side of the transition plate 7 can be abutted against the stop block 206. A support strip plate 702 is extended from the bottom of the transition plate 7 towards the direction close to the carrier vehicle body 2. The transition plate 7 is inclined, and the support strip plate 702 at its bottom is in contact with the ground. By arranging the support strip plate 702, the contact area between the bottom end of the transition plate 7 and the ground is increased, so that the workpiece can bear a certain pressure when sliding on the transition plate 7, in order to improve the service life of the transition plate 7. The transition plate 7 of the present invention can be installed on the left or right side of the carrier vehicle body 2 according to the actual unloading situation, and its installation is relatively convenient. The unloading directions on both sides are not limited, and it is very flexible to use. The load-bearing tires 3 adopt press-fitted tires and can bear a weight of about 60 tons. Protection pads can be arranged on both the ejection plate 4 and the transition plate 7 to reduce the wear of the workpiece.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
