Specific embodiments

[0026] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Embodiment 1: As Figures 1 to 4 shown, a trolley toolbox that can be fixed on a gantry crane includes a toolbox body 1 with a closed structure. The toolbox body 1 includes an upper box body 11 and a lower box body 12 fixed below the upper box body 11. The upper box body 11 and the lower box body 12 have the same width, and the length of the lower box body 12 is greater than that of the upper box body 11. When the two are fixed together, the front side of the lower box body 12 extends horizontally beyond the upper box body 11, and the rear side is flush. Among them, the length, width and height of the upper box body 11 and the lower box body 12 are respectively set according to the circumferential space at the connection with the crane 5. In this embodiment, the length, width and height of the upper box body 11 are 1 * 0.45 * 0.5 m, and the length, width and height of the lower box body 12 are 1.5 * 0.45 * 0.2 m, and various tools with different sizes can be placed. A clamping groove 21 for cooperating with the locking shaft 53 of the crane 5 is provided at the connection between the front side of the lower box body 12 and the upper box body 11. A lock hook plate 3 is installed on the upper box body 11. The clamping groove 21 and the lock hook plate 3 cooperate together to clamp and fix the toolbox body 1 to the surface of the trolley 51 of the crane 5, and the locking shaft 53 is arranged on one side of the trolley 51.

[0028] When installing the toolbox body 1 on the crane 5, first buckle the toolbox body 1 on the crane 5 so that the clamping groove 21 of the toolbox body 1 is cooperatively connected with the locking shaft 53 on the side of the trolley 51. Then, snap the locking hook plate 3 onto the surface of the trolley 51. Thus, the cooperation between the clamping groove 21 and the locking hook plate 3 can fix the toolbox body 1 on the crane 5.

[0029] The toolbox body 1 is provided with an upper box body 11 and a lower box body 12 with different lengths according to the spatial dimensions on the side of the trolley 51, so that it can cooperate with the spatial structure on the side of the trolley 51 of the crane 5, make full use of the remaining space of the crane 5, save space resources, and perfectly cooperate with the crane 5 to form an integral structure, ensuring the overall shape of the two; and setting the upper box body 11 and the lower box body 12 with different lengths is also convenient for storing tools of various sizes. For example, when the length of the lower box body 12 is 1.5 m, it can store long tools such as crowbars and slings; setting the toolbox body 1 with a closed structure can also better avoid the problem of tool scattering caused by bumps during the transfer of tools and appliances and the placement of tools and appliances after work interruption; the cooperation between the clamping groove 21 and the locking hook plate 3 can fix the toolbox body 1 on the crane 5. The toolbox body 1 can be permanently fixed on the trolley 51 and can be directly taken when in use, greatly increasing the convenience of taking tools and appliances, and solving the problems of inconvenience in the transfer process and storage and taking of tools and appliances in the background technology.

[0030] Embodiment 2: On the basis of Embodiment 1, the clamping groove 21 is preferably designed. The clamping groove 21 is a semi-circular arc-shaped structure recessed in the horizontal direction along the inner side of the lower box body 12. Its arc diameter is adapted to the radius of the locking shaft 53, and its length also cooperates with the locking shaft 53. By setting the clamping groove 21 as a semi-circular arc-shaped structure, the clamping groove 21 can better cooperate and connect with the locking shaft 53, maintaining the connection stability of the toolbox body 1 after installation.

[0031] Embodiment 3: On the basis of Embodiment 1, an optimized design is carried out on the connection mode between the toolbox body 1 and the crane 5. The locking hook plate 3 includes an integrally formed long hook plate 31 and a short hook plate 32. The long hook plate 31 and the short hook plate 32 are vertically and fixedly connected to form an L-shaped structure. The long hook plate 31 and the short hook plate 32 are respectively connected to the top surface of the upper box body 11 and the surface of the trolley 51. The specific fixing method is as follows: A threaded hole is provided in the fixed section 311 of the long hook plate 31, and a threaded hole is also provided at the corresponding position on the top surface of the upper box body 11. A bolt passes through the threaded holes of both to fix the long hook plate 31 on the upper box body 11. The connecting section 312 of the long hook plate 31 extends forward in the horizontal direction along the upper box body 11. The short hook plate 32 is connected to the end of the connecting section 312 and extends vertically upward. When the toolbox body 1 is fixed to the crane 5, the short hook plate 32 extends into the gap between the upper surface of the trolley 51 and the balance beam 52. Thus, the clamping groove 21 is lapped on the locking shaft 53, and the locking hook plate 3 is clamped on the surface of the trolley 51. The two cooperate to connect and fix the toolbox body 1 on the trolley 51. Further, two groups of locking hook plates 3 are provided and are respectively fixed on both sides of the surface of the upper box body 11. By providing two groups of locking hook plates 3, the connection stability between the toolbox body 1 and the crane 5 is enhanced.

[0032] When actually installing the toolbox body 1, first remove the locking hook plate 3, turn over the toolbox body 1 so that the clamping groove 21 is aligned with the locking shaft 53, buckle it on the trolley 51, and then put the short hook plates 32 of the two groups of locking hook plates 3 into the gap between the balance beam 52 and the upper surface of the trolley 51 from both sides of the trolley 51, and then fix the long hook plate 31 on the top surface of the upper box body 11 through bolts. Thus, the toolbox body 1 is locked to the trolley 51. This installation method and the detachable connection method of the locking hook plate 3 can avoid the problem that it is inconvenient to install the toolbox body 1 due to the excessive length of the locking hook plate 3.

[0033] Embodiment 4: On the basis of Embodiment 1, an optimized design is carried out on the opening mode of the toolbox body 1. Any one side of the left and right sides of both the upper box body 11 and the lower box body 12 is provided with a box door 13. After the toolbox body 1 is installed, when taking or storing tools, it can be taken or stored unobstructed from both sides of the toolbox body 1. The inner top of the box door 13 is connected to the upper box body 11 or the lower box body 12 through a hinge. The box door 13 opens from top to bottom. After the toolbox body 1 is installed and turned around, it opens and closes in the horizontal direction, making it more convenient to open and close the box door 13.

[0034] Embodiment 5: On the basis of Embodiment 1, an optimized design is carried out. Four casters 14 are also fixedly connected below the four corners of the bottom of the lower box body 12. The setting of the casters 14 enables the toolbox body 1 to be more conveniently transported after being disassembled from the crane 5.

[0035] Embodiment 6: On the basis of Embodiment 5, an optimized design is carried out, such asFigure 4 As shown, a push rod groove 4 is formed at the rear side of the toolbox body 1. A push rod 40 is fixedly connected in the push rod groove 4. The push rod 40 can extend upward out of the push rod groove 4 or retract downward into the push rod groove 4. The specific structure of the push rod 40 is as follows: The push rod 40 includes a movable rod 42 and a fixed rod 43. The movable rod 42 has an inverted U-shaped structure. Its two ends respectively extend into the fixed rod 43 and are slidably connected thereto. The bottom end of the fixed rod 43 is fixed on the inner bottom surface of the push rod groove 4. At both ends of the top of the movable rod 42, buttons 44 are respectively provided. At the bottom of each button 44, a connecting rod 45 is fixedly provided. A fixing plate 46 and a spring 47 are sleeved on the top of the connecting rod 45. The connecting rod 45 can move up and down in the fixing plate 46 and the spring 47. The fixing plate 46 is circumferentially fixed on the inner wall of the movable rod 42. The bottom end of the spring 47 is fixed on the fixing plate 46. The bottom of the connecting rod 45 is fixedly connected to one end of a locking pin 48. The other end of the locking pin 48 passes through the movable rod 42 and extends into a locking hole 49 in the fixed rod 43. The middle of the locking pin 48 is movably connected to one end of a fixing pin 41. The other end of the fixing pin 41 is vertically fixed on the inner wall of the movable rod 42. The locking pin 48 can rotate up and down around the connection with the fixing pin 41. When the button 44 is pressed, it contacts and compresses the spring 47. The connecting rod 45 moves downward and drives the locking pin 48 to rotate clockwise around the fixing pin 41, that is, one end of the locking pin 48 rotates downward and the other end rotates upward. Thus, the other end of the locking pin 48 withdraws from the locking hole 49. At this time, the movable rod 42 can slide in the fixed rod 43 to realize the telescoping of the push rod 40. When the movable rod 42 needs to be fixed, the movable rod 42 is slid to the position where the locking pin 48 is opposite to the locking hole 49, and the locking pin 48 can be locked at the required position. Then the button 44 is released, the spring 47 resets, and the connecting rod 45 drives the other end of the locking pin 48 to snap into the locking hole 49 again to realize the fixing of the push rod 40. Multiple locking holes 49 can be provided, so that the push rod 40 can be adjusted to different heights. Thus, by providing the telescopic push rod 40, when the toolbox body 1 needs to be installed on the crane 5, the movable rod 42 can be retracted into the fixed rod 43, that is, the push rod 40 is pressed down and hidden in the push rod groove 4. When the toolbox body 1 needs to be transported separately, the movable rod 42 is pulled out of the fixed rod 43 and the push rod 40 is held. Thus, the push rod 40 and the caster 14 can be used in cooperation to very conveniently transport the toolbox body 1 separately, and the toolbox body 1 can also be used in a variety of scenarios.

[0036] The above embodiments only represent the specific implementation manners of the present application. The description is relatively specific and detailed, but it cannot be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
