[0026] As Figures 1 - 4 shown, the coal truck unloading tool according to the embodiment of the present utility model may include a holding handle 1, a prying handle 2, a supporting plate 3 and an auxiliary component 4.

[0027] One end of the holding handle 1 is clamped to one end of the prying handle 2, and a prying cavity 21 is formed at the other end of the prying handle 2.

[0028] Further, a clamping groove 22 is formed at one end of the prying handle 2, and the clamping groove 22 is in a T-shaped structure. One end of the holding handle 1 is fixedly connected with a clamping plate matching the clamping groove 22. A holding portion 14 is arranged at the other end of the holding handle 1. The holding portion 14 is an embedded groove, and the edges of the holding portion 14 are all in an arc-shaped structure.

[0029] It should be noted that after one ends of the holding handle 1 and the prying handle 2 described in this embodiment are connected to each other, the connection part is an obtuse angle. The clamping plate and the clamping groove 22 match each other and are both in a T-shaped structure. The outer wall of the holding portion 14 is covered with an anti-slip sleeve, and the protective sleeve can be made of rubber.

[0030] It should be understood that setting the edges of the holding portion 14 in an arc-shaped structure can ensure that it is more convenient for the operator to exert force when holding.

[0031] The supporting plate 3 is installed on the top of the prying handle 2 through a fastening bolt 31.

[0032] Further, a limiting groove 23 is formed at the top of the prying handle 2, and the end of the limiting groove 23 is in an open shape.

[0033] It should be noted that a threaded hole matching the fastening bolt 31 is formed at the top of the prying handle 2 described in this embodiment. During use, it can be removed by screwing the fastening bolt 31, and then the whole on the supporting plate 3 can be removed from the limiting groove 23, so as to facilitate the replacement of parts, and the practicability is ensured.

[0034] The auxiliary component 4 includes an adjusting screw rod 41, a threaded sleeve 42, a connecting arm 43, a lower pressing plate 44 and a lower pressing pad 45.

[0035] One end of the adjusting screw rod 41 is rotatably connected to the top of the supporting plate 3, and the threaded sleeve 42 is threadedly sleeved on the adjusting screw rod 41.

[0036] It should be noted that the other end of the adjusting screw rod 41 described in this embodiment is fixedly connected with an adjusting head, and anti-slip lines are arranged on the outer wall of the adjusting head in a circumferential array.

[0037] There are two connecting arms 43. One ends of the two connecting arms 43 are symmetrically and fixedly connected to the outer wall of the threaded sleeve 42. The other ends of the connecting arms 43 slide through the top of the supporting plate 3 and are connected to the top of the lower pressing plate 44. The lower pressing pad 45 is fixedly connected to the bottom of the lower pressing plate 44.

[0038] It should be noted that the connecting arm 43 described in this embodiment has an L-shaped structure. At the same time, when the lock rod is pried multiple times, the pressing pad 45 will be worn. Therefore, positioning sleeves are symmetrically and rotatably connected to the top of the lower pressing plate 44. A limit bolt is installed on the outer wall of the positioning sleeve, and a threaded hole matching the limit bolt is provided on the outer wall of the end of the connecting arm 43. When the pressing pad 45 needs to be replaced, the limit bolt can be screwed to disconnect the end of the connecting arm 43 from the positioning sleeve, and then the entire lower pressing plate 44 can be replaced.

[0039] Furthermore, as Figure 1 shown, the inner bottom of the opening of the prying bin 21 is a cut surface structure. An auxiliary block 13 is fixedly connected to the bottom of the holding handle 1. The bottom of the auxiliary block 13 is parallel to the bottom of the prying handle 2. At the same time, the end cut surface of the auxiliary block 13 is parallel to the end cut surface of the prying handle 2.

[0040] It should be noted that in order to facilitate the prying bin 21 to be sleeved on the lock rod in this embodiment, first place the opening of the prying bin 21 at the end of the lock rod, and then use an external tool, such as a hammer, to strike the auxiliary block 13, so that the prying bin 21 can be more efficiently sleeved on the lock rod. Since the inner bottom of the opening of the prying bin 21 is a cut surface structure, the sleeving process is more convenient.

[0041] Specifically, after the coal transport vehicle arrives at the designated location, first open the rear door of the cargo compartment. In order to safely and quickly lift the rear door lock rod, since one end of the holding handle 1 is clamped with one end of the prying handle 2, a prying bin 21 is provided at the other end of the prying handle 2. The supporting plate 3 is installed on the top of the prying handle 2 through a fastening bolt 31. One end of the adjusting screw rod 41 is rotatably connected to the top of the supporting plate 3. The threaded sleeve 42 is threadedly sleeved on the adjusting screw rod 41. There are two connecting arms 43. One ends of the two connecting arms 43 are symmetrically and fixedly connected to the outer wall of the threaded sleeve 42. The other ends of the connecting arms 43 slide through the top of the supporting plate 3 and are connected to the top of the lower pressing plate 44. The pressing pad 45 is fixedly connected to the bottom of the lower pressing plate 44. Therefore, after the prying bin 21 is first sleeved on the lock rod, by screwing the adjusting screw rod 41, under the limitation of the connecting arm 43, the position of the threaded sleeve 42 can be adjusted up and down. When the threaded sleeve 42 moves downward, under the action of the connecting arm 43, the lower pressing plate 44 can be driven to move downward. Finally, the lock rod is pressed by the pressing pad 45, so as to ensure a tighter fit with the lock rod. Subsequently, by applying force to the holding handle 1, the lock rod can be opened using the lever principle, thus avoiding the problem of slipping and ensuring the safety of the operator and the goods.

[0042] In an embodiment of the present invention, as Figures 1 - 4As shown in the figure, connecting sleeves 11 are symmetrically and fixedly connected to both sides of the outer walls of one end of the holding handle 1 and the prying handle 2.

[0043] It should be noted that a damping pad is fixedly connected to the inner wall of the connecting sleeve 11 described in this embodiment. The damping pad can ensure the fastening effect of the reinforcing arm 12. At the same time, under the action of the reinforcing arm 12, the connection strength between the holding handle 1 and the prying handle 2 is also ensured.

[0044] In summary, for the coal transport vehicle unloading tool according to the embodiment of the present invention, first, after the prying bin 21 is sleeved on the locking rod, by turning the adjusting screw rod 41, the position of the threaded sleeve 42 can be adjusted up and down under the limiting action of the connecting arm 43. When the threaded sleeve 42 moves downward, it can drive the lower pressing plate 44 to move downward under the action of the connecting arm 43. Finally, it presses on the locking rod through the pressing pad 45, thereby ensuring a closer fit with the locking rod. Subsequently, by applying force to the holding handle 1, the locking rod can be opened using the lever principle, thus avoiding the problem of slipping, and ensuring the safety of the operator and the goods.
