Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0048] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the usual meanings understood by persons of ordinary skill in the field to which this utility model belongs. The words "first", "second" and similar terms used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0049] The following first describes in detail the trolley track maintenance platform according to an embodiment of the utility model with reference to the accompanying drawings.

[0050] According to the trolley track maintenance platform of the embodiment of the present utility model, Figure 1 and Figure 3 As shown, it may include: a maintenance platform body 100 , a wheel set 300 and a telescopic device 400 .

[0051] Wheel assemblies 300 are mounted on both sides of the maintenance platform body 100 and are used to rollably connect to a pair of trolley rails 200. As an example, the pair of trolley rails 200 are respectively mounted on the inner side of the beam 500, and the maintenance platform body 100 is rollably connected to the trolley rails 200 via the wheel assemblies to perform maintenance on the trolley rails 200.

[0052] The telescopic device 400 is provided on the maintenance platform body 100 corresponding to the wheel set 300 , and the wheel set 300 is connected to the maintenance platform body 100 via the telescopic device 400 .

[0053] The telescopic device 400 is used to drive the wheel set 300 to telescope relative to both side ends of the maintenance platform body 100 .

[0054] That is, according to the embodiment of the trolley track maintenance platform of the present invention, telescopic devices 400 are respectively provided on both side ends of the maintenance platform body 100, and the wheel assemblies 300 are connected to both side ends of the maintenance platform body 100 through the telescopic devices 400. The telescopic devices 400 drive the wheel assemblies 300 to telescope relative to both side ends of the maintenance platform body 100, so as to adjust the distance between the wheel assemblies 300 on the maintenance platform body 100. Thus, when the hoisting device sets the entire maintenance platform body 100 on the trolley track 200 on the inner side of the beam 500, the wheel assemblies 300 can be adjusted to a retracted state in advance, until the trolley track maintenance platform reaches a predetermined height above the trolley track 200, and then the relative distance between the wheel assemblies 300 is adjusted to match the spacing between the pair of trolley tracks 200, and finally the maintenance platform body 100 is rolled onto the pair of trolley tracks 200, completing the hoisting and maintenance.

[0055] That is to say, according to the trolley track maintenance platform of the embodiment of the present invention, the relative spacing of the wheel group 300 can be adjusted to achieve the wheelbase adjustment of the maintenance platform body 100 to the preset track gauge between the trolley tracks 200 on the beam 500. The structure is reliable and safe, and the trolley track maintenance platform can be conveniently and efficiently hoisted and put into use to maintain the trolley track 200.

[0056] In some embodiments, as Figure 1 and Figure 3 As shown, the maintenance platform body 100 may include a main working platform 110 and a pair of connecting platforms 120. The pair of connecting platforms 120 are respectively provided at both ends of the main working platform 110.

[0057] The wheel set 300 and the telescopic device 400 are respectively disposed on a pair of connecting platforms 120 .

[0058] That is to say, the maintenance platform body 100 includes a main working platform 110 and a pair of connecting platforms 120 respectively connected to the two side ends of the main working platform 110. By arranging the wheel groups 300 and the telescopic devices 400 relatively on the pair of connecting platforms 120, the main working platform 110 is erected on a pair of trolley rails 200 through the wheel groups 300 and the telescopic devices 400 on the pair of connecting platforms 120.

[0059] It should be noted that the pair of connecting platforms 120 can be respectively provided on the surfaces of both side ends of the main working platform 110 , for example, and the present invention does not impose any specific limitation on this.

[0060] In some embodiments, the wheel set 300 may include four wheel assemblies, and the four wheel assemblies are respectively disposed on a pair of connecting platforms 120 in pairs.

[0061] Among them, the four wheel assemblies include a driving wheel assembly and a driven wheel assembly.

[0062] As an example, Figure 1 and Figure 3 As shown, four wheel assemblies are arranged in a rectangular shape at the four corners of a pair of connecting platforms 120 to provide rolling support for the maintenance platform body 100. Among them, one wheel assembly on both sides of the pair of connecting platforms 120 is selected as the active wheel assembly to drive the driven wheel assemblies at the other two corners of the pair of connecting platforms 120 to roll.

[0063] In some embodiments, as Figure 1 and Figure 3 As shown, the telescopic devices 400 may include four, and the four wheel assemblies are respectively connected to the outer ends of the connecting platform 120 through the telescopic devices 400 and can be telescoped relative to the outer ends of the connecting platform 120.

[0064] That is to say, the four telescopic devices 400 are respectively installed at the four corners of a pair of connecting platforms 120, and the four wheel assemblies are respectively connected to the outer ends of the connecting platforms 120 through the telescopic devices 400. The telescopic devices 400 drive the axially opposite wheel assemblies to telescope relative to the outer ends of the connecting platforms 120, thereby finally realizing the wheelbase adjustment of the wheel assemblies on the maintenance platform body 100, which is simple and reliable.

[0065] In some embodiments, as Figure 2 as well as Figure 5-Figure 7 As shown, the telescopic device 400 may include: a pair of slide rails 410 , a slide plate 420 and a driving cylinder 430 .

[0066] The pair of slide rails 410 are disposed on the connecting platform 120 along the inner side-outer side direction of the connecting platform 120 .

[0067] Both sides of the slide plate 420 are slidably connected to opposite sides of a pair of slide rails 410 . A connecting portion 422 is further provided at the bottom of the slide plate 420 , and a wheel assembly is provided on the top surface of the slide plate 420 .

[0068] The driving cylinder 430 is arranged on the connecting platform 120 and is located at the bottom of the slide 420. The telescopic direction of the driving cylinder 430 is parallel to the length direction of the slide rail 410. The telescopic end of the driving cylinder 430 is arranged close to the outer end of the connecting platform 120. The telescopic end of the driving cylinder 430 is pinned to the connecting part 422 to drive the slide 420 to slide along the slide rail 410.

[0069] That is to say, a pair of slide rails 410 extending along the inner-outer direction of the connecting platform 120 are provided, and a skateboard 420 is slidably connected between the pair of slide rails 410, and a wheel assembly is provided on the skateboard 420. A driving cylinder 430 is provided at the bottom of the skateboard 420 on the connecting platform 120 and is arranged in the same direction as the slide rails 410. The telescopic end of the driving cylinder 430 is close to the outer end of the connecting platform 120, and a connecting portion 422 is provided at the bottom of the skateboard 420 to pin the telescopic end of the driving cylinder 430. The driving cylinder 430 drives the skateboard 420 to slide along the inner-outer direction of the connecting platform 120 between the pair of slide rails 410, thereby driving the wheel assembly on the skateboard 420 to extend toward the outer end of the connecting platform 120 and retract toward the inner side of the connecting platform 120.

[0070] In some embodiments, as Figure 7 As shown, a pair of slide rails 410 are provided with guide grooves 411 along their length directions on opposite sides thereof.

[0071] The telescopic device 400 may further include a pair of sliders 440 , wherein the pair of sliders 440 are respectively connected to both side ends of the slide plate 420 , and the pair of sliders 420 are respectively slidably connected to the pair of guide grooves 411 .

[0072] Specifically, guide grooves 411 are defined on opposing sides of a pair of slide rails 410, and a slider 420 is slidably disposed within each of the guide grooves 411. The two side ends of the slider 420 are connected to the sliders 420 within the guide grooves 411, thereby enabling the slider 420 to slide stably and reliably between the pair of slide rails 410, significantly reducing wear on the slider 420 and increasing its service life. Preferably, the drive cylinder 430 is disposed between the pair of slide rails 410 and parallel to the direction in which the guide grooves 411 are formed, thereby improving drive efficiency.

[0073] In other embodiments, Figure 5 and Figure 7As shown, a plurality of positioning holes 470 can also be provided at the connection between the skateboard 410 and the slider 440 at intervals along the extension direction of the slide rail 410. The positioning holes 470 can be, for example, blind holes. The positioning holes 470 can be opened from the upper surface or lower surface of the slider 440 to the skateboard 410 layer. The length of the positioning hole 470 is the thickness of the skateboard 410 plus the thickness of the upper half layer or lower half layer of the slider 440 relative to the skateboard 410, and a hole is opened at the position of the positioning hole 470 on the upper side wall of the slide rail 410, thereby allowing the positioning pin 450 to pass through the upper side wall of the slide rail 410 and be inserted into the positioning hole 470 to achieve the positioning of the skateboard 420, thereby achieving the telescopic positioning of the wheel assembly.

[0074] In some embodiments, as Figure 8 and Figure 9 As shown, the telescopic device 400 further includes a pair of limiting devices 460 , which are sequentially arranged on the slide rail 410 on one side along the length direction of the slide rail 410 , and the limiting devices 460 are used to perform limit detection on the movement of the wheel assembly.

[0075] Specifically, a pair of limit devices 460 are sequentially provided on the slide rail 410 on one side of the telescopic device 400 to detect and limit the sliding position of the wheel assembly relative to the slide rail 410. For example, one limit device 460 is provided at one end of the slide rail 410 near the inner side of the connection platform 120, and a second limit device 460 is provided at the other end of the slide rail 410 opposite the first limit device 460. The spacing between the two limit devices 460 is controlled to be 250-300 cm, thereby enabling travel detection of the end of the wheel assembly near the inner side of the connection platform 120.

[0076] In some embodiments, as Figure 5 and Figure 6 As shown, the wheel assembly 300 may include a base 310 , a roller 320 and a wheel 330 .

[0077] The base 310 is disposed on the top surface of the slide plate 420 .

[0078] The roller 320 is disposed inside the base 310 in parallel with the slide rail 410 , and one end of the roller 320 extends out of an end of the base 310 close to the outer end of the connecting platform 120 .

[0079] The wheel 330 is connected to one end of the roller 320 extending from the base 310 , and the wheel 330 is used to be connected to the trolley track 200 for rolling.

[0080] The active wheel assembly further includes a hydraulic motor 340 , which is connected to one end of the roller 320 located inside the base 310 .

[0081] Therefore, the wheel assembly 300 has a simple and reliable structure and is easy to disassemble and maintain.

[0082] In some embodiments, as Figure 1-Figure 4 As shown, the main working platform 110 is equipped with a control cabinet 130, a hydraulic station 140, and a cable reel 150. The control cabinet 130 is used to control the overall operation of various devices on the trolley track maintenance platform. The hydraulic station 140 is used to hydraulically control various drive sources on the trolley track maintenance platform, such as the drive cylinder 430 and hydraulic motor 340. The cable reel 150 is used to connect to the power socket of the quay crane to provide power to the maintenance platform.

[0083] The connecting platform 120 is also equipped with a lifting beam 170, a roller assembly 180, and a rail clamp 190. The lifting beam 170 is used to lift the trolley track and trolley track accessories that need maintenance; the roller assembly 180 is used to support the quay crane trolley and the bracket wire rope to prevent interference between the maintenance platform and the wire rope; the rail clamp 190 is used to clamp the trolley track that needs maintenance and replacement. It is generally connected to each side of a pair of connecting platforms 120.

[0084] Specifically, if Figure 10 As shown, the rail clamping device 190 includes a clamping jaw 191, a mounting seat 192 and a push rod 193. The clamping jaw 191 is connected to one end of the mounting seat 192, and the push rod 193 passes through the connecting clamping jaw 191 from the other end of the mounting seat 192. The push rod 193 is manually pushed and pulled to achieve clamping and release of the trolley track.

[0085] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
