Description

Technical Field

[0001] The present invention belongs to the technical field of mining equipment, and particularly relates to a tipping trolley for ore transportation. Background Art

[0002] During the transportation and mining process in a mining area, the ore in a mine or a shaft needs to be transported out in time. In order to facilitate the temporary transfer of the ore, a trolley is often used. A trolley is a handling vehicle that is pushed and pulled by manpower.

[0003] For example, Chinese Utility Model CN221293633U discloses an adjustable trolley for mining. By means of an adjustment mechanism, the angle of the hopper can be adjusted in real time, so that the ore inside the hopper is prevented from moving randomly due to the slope inclination, thereby improving the stability of the trolley. And the adjustment mechanism can adjust the hopper up and down, thus improving the practicability of the trolley.

[0004] However, the existing trolleys have relatively single functions, and it is inconvenient to unload the ore in the trolley. It cannot be directly unloaded manually, and the ore inside the trolley cannot be completely unloaded by tools, etc., resulting in poor overall usability. Summary of the Invention

[0005] The purpose of the present invention is to provide a tipping trolley for ore transportation. By hinging the end of the armrest bracket to the lower surface of the hopper frame away from the front wheel, when the trolley handle is pressed down, the armrest bracket is used to lift one end of the hopper frame upwards, so that the hopper tilts to achieve unloading, solving the problem of poor usability of the existing trolleys.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a tipping trolley for ore transportation, including a hopper frame and an armrest bracket. A hopper is fixedly connected to the upper surface of the hopper frame, and front wheels are installed at one end thereof; the armrest bracket has two trolley handles, and a pair of rear wheels are installed on the armrest bracket; the end of the armrest bracket is hinged to the lower surface of the hopper frame away from the front wheel end, so that under the action of gravity, the lower surface of the hopper frame fits with the upper surface of the armrest bracket, and when the trolley handle is pressed down, the armrest bracket is used to lift one end of the hopper frame upwards, so that the hopper tilts to achieve unloading.

[0008] As a preferred technical solution of the present invention, a locking mechanism is further included for keeping the hopper frame and the armrest bracket in a fitting state through the locking mechanism.

[0009] As a preferred technical solution of the present invention, the locking mechanism includes a pair of locking blocks fixed to the lower surface of the bucket frame, and a pair of mounting blocks fixedly connected to the armrest bracket, and the mounting blocks and the locking blocks are arranged in a staggered manner; a locking insertion hole is formed on the side surface of the locking block, and a locking insertion rod is movably inserted through the mounting block. By inserting the locking insertion rod into the locking insertion hole, the relative position between the bucket frame and the armrest bracket is fixed.

[0010] As a preferred technical solution of the present invention, a mounting plate is fixedly connected between the two mounting blocks, a rotating shaft is rotatably connected to the mounting plate, and a transmission gear is fixedly connected to the upper end of the rotating shaft; opposite ends of the two locking insertion rods are fixedly connected with racks meshing with the transmission gear, so as to drive the two locking insertion rods to move away from and towards each other synchronously by rotating the rotating shaft and using the transmission of the transmission gear and the racks.

[0011] As a preferred technical solution of the present invention, a driven wheel is fixedly connected to the lower end of the rotating shaft, the mounting plate is fixedly connected with a plurality of side plates, and a straight rack is movably inserted through the side plates; the straight rack meshes with the driven wheel, and the rotating shaft is rotated by pushing and pulling the straight rack.

[0012] As a preferred technical solution of the present invention, a guide rod is fixedly connected to one end of the straight rack, a spring is sleeved on the guide rod, and one end of the spring abuts against the end face of the straight rack and the other end abuts against the side plate, so as to push the straight rack to reset by the spring after pulling the straight rack.

[0013] As a preferred technical solution of the present invention, a pull rope is connected to one end of the guide rod, and the other end of the pull rope is connected to the push cart handle, so as to facilitate pulling the straight rack by the pull rope.

[0014] As a preferred technical solution of the present invention, a pull rod is connected to the push cart handle, and one end of the pull rope is connected to the pull rod.

[0015] As a preferred technical solution of the present invention, a plurality of guide wheels are connected to the armrest bracket and the two push cart handles, and the pull rope is supported and guided by the guide wheels, so that the pulling force of the pull rope on the guide rod is parallel to the length direction of the guide rod.

[0016] As a preferred technical solution of the present invention, a connecting rod is fixedly connected to the guide rod, and a horizontal rod is provided at the upper end of the connecting rod; an inclined plate corresponding to the position of the horizontal rod is fixedly connected to the bucket frame. When the bucket frame rotates from an inclined state to a horizontal state, the horizontal rod is squeezed by the inclined plate, so that the guide rod pulls the straight rack to move, and the locking insertion rod moves to avoid the locking block; wherein, when the bucket frame rotates to the horizontal state, the horizontal rod loses the block of the inclined plate, and the spring pushes the straight rack to reset, so that the locking insertion rod is inserted into the locking insertion hole of the locking block.

[0017] The present invention has the following beneficial effects:

[0018] In the present invention, a front wheel is installed at one end of the hopper frame, and a pair of rear wheels are installed on the armrest bracket. The end of the armrest bracket is hinged to the lower surface of the hopper frame at the end away from the front wheel. Under the action of gravity, the lower surface of the hopper frame fits with the upper surface of the armrest bracket. When the push handle is pressed down, the hopper frame is jacked up at one end by the armrest bracket, causing the hopper to tilt and realizing unloading, thereby achieving the function of manual and rapid unloading, effectively improving the overall convenience of use.

[0019] Of course, not necessarily all the advantages described above need to be achieved simultaneously when implementing any product of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 the 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.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 3 As shown, the present invention is a tipping trolley for ore transportation, including a bucket frame 1 and an armrest bracket 2. The upper surface of the bucket frame 1 is fixedly connected with a bucket 101, and a front wheel 102 is installed at one end of the bucket frame 1.

[0035] The armrest bracket 2 has two push handles 201, and the height of the push handles 201 in the vertical direction is higher than the height of the bucket 101. Moreover, a pair of rear wheels 202 are installed on the armrest bracket 2. The end of the armrest bracket 2 is hinged to the lower surface of the end of the bucket frame 1 far from the front wheel 102, so that under the action of gravity, the lower surface of the bucket frame 1 fits with the upper surface of the armrest bracket 2. As shown in the figure, after the lower surface of the bucket frame 1 fits with the upper surface of the armrest bracket 2, both are in a horizontal state. And when the bucket 101 is loaded with ore raw materials, due to the large weight, the bucket frame 1 and the armrest bracket 2 are relatively more stable.

[0036] As Figure 8As shown in the figure, when discharging is required, when pressing down the cart handle 201, the armrest bracket 2 rotates with the rear wheel 202 as the fulcrum, so that one end of the hopper frame 1 is lifted upwards by using the armrest bracket 2. During the rotation process of the hopper frame 1 with the front wheel 102 as the fulcrum, the hopper 101 tilts to achieve discharging. Since the cart handle 201 extends away from the rear wheel 202, the lever principle is used to achieve the effect of saving effort. The center of the hopper 101 after loading ore raw materials is usually located at the center position of the hopper frame 1, and the hopper frame 1 rotates with the front wheel 102 as the fulcrum, also using the lever principle to play a role in saving effort, so that the user can manually press down the cart handle 201 to rotate the hopper frame 1 and pour the ore raw materials in the hopper 101, thus effectively improving the overall usability.

[0037] Embodiment 2

[0038] As Figures 4 to 6 shown in the figure, it further includes a locking mechanism for keeping the hopper frame 1 and the armrest bracket 2 in a fitting state through the locking mechanism, such as connecting and fixing by a lock. The locking mechanism in this embodiment includes a pair of locking blocks 103 fixed to the lower surface of the hopper frame 1, and a pair of mounting blocks 203 fixedly connected to the armrest bracket 2. The mounting blocks 203 and the locking blocks 103 are arranged in a mutually staggered manner.

[0039] A locking insertion hole 104 is formed on the side surface of the locking block 103, and a locking insertion rod 3 is movably inserted through the mounting block 203. By inserting the locking insertion rod 3 into the locking insertion hole 104, the relative positions of the hopper frame 1 and the armrest bracket 2 are fixed. When discharging, pull the locking insertion rod 3 to pull the locking insertion rod 3 out of the locking insertion hole 104, and then the hopper frame 1 and the armrest bracket 2 can be rotated.

[0040] Wherein, a mounting plate 204 is fixedly connected between the two mounting blocks 203, a rotating shaft 4 is rotatably connected to the mounting plate 204, and a transmission gear 401 is fixedly connected to the upper end of the rotating shaft 4. Opposite ends of the two locking insertion rods 3 are fixedly connected with racks 301 meshing with the transmission gear 401, so as to drive the two locking insertion rods 3 to move away from and towards each other synchronously by rotating the rotating shaft 4 and using the transmission of the transmission gear 401 and the racks 301. Thus, by rotating the rotating shaft 4, the two locking insertion rods 3 can be pulled out of the locking insertion holes 104 at the same time, and when the rotating shaft 4 rotates in the reverse direction, the two locking insertion rods 3 can be inserted into the locking insertion holes 104 at the same time, thereby further improving the usability.

[0041] As another preferred embodiment, as Figure 4As shown, a driven wheel 402 is fixedly connected to the lower end of the rotating shaft 4. The mounting plate 204 is fixedly connected with two side plates 403, and a straight rack 404 is movably inserted through the side plates 403. The straight rack 404 can be a cylindrical rack. The straight rack 404 meshes with the driven wheel 402, and the rotating shaft 4 is rotated by pushing and pulling the straight rack 404.

[0042] Wherein, one end of the straight rack 404 is fixedly connected with a guide rod 405. A spring 406 is sleeved on the guide rod 405. One end of the spring 406 abuts against the end face of the straight rack 404, and the other end abuts against the side plate 403. After the straight rack 404 is pulled, the spring 406 is compressed, and then the straight rack 404 is pushed by the spring 406 to realize automatic reset.

[0043] At the same time, one end of the guide rod 405 is connected with a pull rope 5, and the other end of the pull rope 5 is connected to the cart handle 201, which is convenient for pulling the straight rack 404 through the pull rope 5. Specifically, the cart handle 201 is connected with a pull rod 501, and one end of the pull rope 5 is connected to the pull rod 501. The armrest bracket 2 and the two cart handles 201 are both connected with a plurality of guide wheels 502, and the pull rope 5 is supported and guided by the guide wheels 502, so that the tensile force of the pull rope 5 on the guide rod 405 is parallel to the length direction of the guide rod 405.

[0044] As Figure 6 shown, when discharging is required, the pull rope 5 is pulled through the pull rod 501 at the position of the cart handle 201, the straight rack 404 is pulled by the pull rope 5, and then the two locking bolts 3 are synchronously driven to move through the transmission between the transmission gear 401 and the rack 301, and are pulled out from the locking holes 104 of the locking block 103 to realize unlocking. Thus, the convenience of operation is further improved.

[0045] Embodiment 3

[0046] As Figure 7 shown, on the basis of Embodiment 2, the guide rod 405 is welded or screwed with a connecting rod 601, and the upper end of the connecting rod 601 has a horizontal rod 602; a plurality of rollers are installed on the horizontal rod 602.

[0047] The hopper frame 1 is fixedly connected with an inclined plate 6 corresponding to the position of the horizontal rod 602. When the hopper frame 1 rotates from an inclined state to a horizontal state after discharging, the horizontal rod 602 is squeezed by the inclined plate 6, so that the guide rod 405 pulls the straight rack 404 to move, and the locking bolt 3 moves, that is, from the position in Figure 5 to the position in Figure 6 to avoid the locking block 103, so that the hopper frame 1 can freely fall without manually maintaining the state of pulling the pull rope 5.

[0048] Among them, when the bucket frame 1 rotates to the horizontal state, that is, the locking jack 104 of the mounting block 203 corresponds to the position of the locking plug 3. At this time, the horizontal rod 602 loses the block of the inclined plate 6, and the straight rack 404 is pushed back by the spring 406, so that the locking plug 3 is inserted into the locking jack 104 of the locking block 103, completing the locking of the position between the bucket frame 1 and the armrest bracket 2.

[0049] By setting the inclined plate 6, the connecting rod 601 and the horizontal rod 602, it only needs to pull the pull rope 5 during unloading. The bucket frame 1 and the armrest bracket 2 can be flipped and reset by the inclined plate 6 pushing the horizontal rod 602, realizing the movement of the straight rack 404, that is, completing the avoidance of the locking plug 3 from the locking block 103, thus greatly improving the convenience of use.
