With the popularization of winter sports, the industry chain continues to extend, encompassing multiple sectors such as winter sports equipment manufacturing, winter sports tourism, and winter sports events.

[0003] The development of the ice and snow industry has not only promoted the coordinated development of related industries, but also injected new impetus into economic growth, becoming an important part of the sports industry and cultural tourism industry, and has broad development prospects.

[0004] Currently, the equipment used in ice and snow venues has limited functionality and cannot meet diverse needs. For example, in ice and snow sports venues, tasks such as snow removal, ice clearing, and venue leveling typically require different equipment. Switching between and operating these devices is cumbersome, leading to low work efficiency and increased labor and time costs. Traditional maintenance methods are inefficient and time-consuming, taking 1-2 hours in total, severely impacting the operational efficiency and user experience of ice and snow sports venues. Furthermore, traditional equipment requires the collaboration of multiple people, including professional drivers, ice surface maintenance personnel, and equipment operators, resulting in high labor costs and low equipment utilization. In the operation of ice and snow sports venues, equipment operation and maintenance require professional personnel, which not only increases labor costs but also limits equipment utilization efficiency.

[0005] Therefore, the purpose of this invention is to optimize the functions of working equipment in ice and snow venues, and to modularize the design of various functional accessories so that different functional accessories can be replaced according to different working conditions.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] refer to Figures 1-3 A modular boom mechanism suitable for ice and snow venues includes a bracket 1 and a connecting frame 2 located in the middle of the bracket 1. The rear end of the bracket 1 is provided with a boom 31 connecting part 11, and the rear end of the connecting frame 2 is provided with a tie rod 33 connecting part 21. The front end of the bracket 1 is provided with symmetrically arranged first connecting parts 12 for connecting a first functional accessory. The front end of the connecting frame 2 is provided with a second connecting part 22 for connecting a second functional accessory. By connecting the first functional accessory through the first connecting part 12 or connecting the second functional accessory through the second connecting part 22, the boom mechanism can have the function of the first functional accessory or the second functional accessory.

[0032] In this design, the rear end of the bracket 1 is connected to the boom 31 of the external vehicle body 3 through the boom 31 connecting part 11, and the rear end of the connecting frame 2 is connected to the tie rod 33 of the external vehicle body 3 through the tie rod 33 connecting part 21. The symmetrically arranged first connecting parts 12 at the front end of the bracket 1 are used to connect the first functional attachment, which specifically includes one of a sweeping module, a leveling module, or a transport module, used for sweeping, de-icing, leveling, and transporting on ice and snow surfaces. This type of attachment has a large working range, and its working width is almost greater than the width of the vehicle body, so two first connecting parts 12 are required for connection. The second connecting part 22 at the front end of the connecting frame 2 is used to connect the second functional attachment, which specifically includes attachments with a smaller working range, such as a hydraulic breaker E. The volume of the second functional attachment is smaller than that of the first functional attachment, so it cannot be directly connected to the symmetrically arranged first connecting parts 12. If only a single first connecting part 12 is connected, the overall boom mechanism will be unbalanced in terms of force, affecting the safety of the operation. Therefore, the second connecting frame 2 has been improved. Because the connecting frame 2 is located in the middle of the bracket 1, after the second functional attachment is connected, the second functional attachment can also be located in the middle position, ensuring the balance of force on the boom mechanism.

[0033] Preferably, the bracket 1 includes a first frame 13 and a connecting rod 14 arranged symmetrically. The first connecting part 12 and the boom 31 connecting part 11 are both located on the first frame 13. There are at least two connecting rods 14. The connecting rods 14 are connected between the symmetrically arranged first frames 13. The connecting frame 2 passes through the connecting rods 14 and is fixedly connected to the connecting rods 14.

[0034] Specifically, both first frames 13 are connected to the boom 31 via the boom 31 connecting part 11. The two first frames 13 are connected by a connecting rod 14, which enables the two first frames 13 to become a whole. The swing of the first frame 13 is mainly driven by the connecting frame 2. By passing the connecting frame 2 through the two connecting rods 14, it is equivalent to fixing the connecting frame 2 between the two first frames 13. By driving the connecting frame 2 to swing through the pull rod 33, the two first frames 13 can be driven to swing synchronously, so as to adjust the working angle of the first functional accessory and the working angle of the second functional accessory.

[0035] Furthermore, the first frame 13 includes symmetrically arranged first plates 131, support rods 132 connected between the first plates 131, and a first fixing rod 133 passing through the first plates 131. The first fixing rod 133 is located at the rear end of the first plates 131, and the support rod 132 is located at the front end of the first plates 131. The first fixing rod 133 is a boom 31 connecting part 11. A through hole 134 is also provided at the front end of the first plates 131. The through hole 134 is located below the support rod 132. The through hole 134 and the support rod 132 form a first connecting part 12. The first fixing rod 133 is connected to the first plates 131. The bracket 1 also includes a first hydraulic cylinder 15, which is horizontally arranged. The cylinder body of the first hydraulic cylinder 15 is connected to the connecting frame 2. The first hydraulic cylinder 15 has two output ends 151, which are matched with through holes 134 on two first frame bodies 13 respectively. The first hydraulic cylinder 15 is used to pass through the through holes 134 to fix the first functional accessory on the bracket 1.

[0036] Specifically, the first hydraulic cylinder 15 can be connected to the connecting frame 2 by welding. It is known that, in the initial stage, both output ends 151 of the first hydraulic cylinder 15 are located between the two first frames 13.

[0037] The structure of the first frame 13 can be referenced to the technical solution disclosed in Chinese Patent CN119041516A. In this embodiment, the described rear end and front end of the first plate 131 refer to the rear end and front end of the two first plates 131 on a single first frame 13. Therefore, the first fixing rod 133 passing through the first plate 131 connects to the boom 31 in such a way that the end of the boom 31 is hinged to the first fixing rod 133 by being embedded between the two first plates 131. The support rod 132 located at the front end of the first plate 131 is used to connect to the first functional accessory. The first functional accessory is described with reference to bucket A. The specific structure of bucket A is described in Chinese Patent CN11904. As described in 1516A, the specific connection method is as follows: two hooks a and two ear plates b are provided on the bucket A. The ear plates b have hinge holes. The hooks a are matched with the support rod 132, so that the hooks a are hooked on the support rod 132 and lifted by the support rod 132. Then, under the action of the pull rod 33, the first frame 13 is swung towards the ear plates b, and the ear plates b at the corresponding positions are embedded between the two first plates 131. Then, the first hydraulic cylinder 15 drives its two output ends 151 to extend, locking the two ear plates b into the two first frames 13 respectively, thus completing the connection. Based on this connection method, two hooks a and two ear plates b are also provided in the sweeping module, leveling module or transportation module to achieve the purpose of quick change.

[0038] It should also be noted that the sweeping module can be a sweeping roller assembly B, a bucket A, or a bucket A with a clamping function. Specifically, the sweeping roller assembly B includes a housing B1 and a brush roller B3 rotatably connected within the housing B1. The housing B1 is equipped with a drive motor B2 for driving the brush roller B3. The housing B1 also has two hooks a and two ear plates b, allowing for quick assembly as described above. The drive motor B2 is powered by a power supply module on the vehicle body 3. Regarding the bucket A with the clamping function, it has two hooks a and two ear plates b, allowing for quick assembly as described above. The bucket A also has clamping claws and a clamping drive cylinder. The clamping claws are hinged to the bucket A, and the cylinder body of the clamping drive cylinder is connected to the bucket A. The clamping drive cylinder can be driven by an oil supply module on the vehicle body 3.

[0039] The leveling module can be either a pressure roller assembly D or a bucket A. The pressure roller assembly D includes an outer shell B1 and a pressure roller rotatably connected inside the outer shell B1. The outer shell B1 is provided with two hooks a and two ear plates b, which are quickly installed in the manner described above.

[0040] The transport module can be a transport rack C, specifically a transport rack C on a forklift. The transport rack C is equipped with two hooks a and two lugs b, which are used for quick loading in the manner described above.

[0041] It should also be noted that this application is not limited to using the above three modules. The function of the modules is not limited in this application. The description of the above three modules is only to illustrate that other modules with two hooks a and two ear plates b can also be quickly installed in the above manner, and this quick installation method is also the prior art.

[0042] Furthermore, the connecting frame 2 includes symmetrically arranged second plates 23, both of which are threaded through the connecting rod 14. The front end of the second plate 23 is provided with a connecting hole 231, and there are two connecting holes 231 on a single second plate 23. The connecting holes 231 are located at the front end of the second plate 23 and are second connecting parts 22. A second fixing rod 232 is threaded through the rear end of the second plate 23 and is a connecting part 21 of the pull rod 33.

[0043] In this embodiment, the main function of the second connecting part 22 is to connect the hydraulic breaker E. Based on the above-mentioned quick-installation design, this application improves the structure of the connecting frame 2. Specifically, a connecting hole 231 is provided at the front end of the connecting frame 2, and the position of the connecting hole 231 matches the mounting hole E1 of the external hydraulic breaker E. For the structure of the hydraulic breaker E, please refer to Chinese Patent CN118241714A. To avoid interference with the first functional accessory, preferably, in the vertical projection, the front end of the second plate 23 does not extend beyond the front end of the first plate 131. Based on the structure of the hydraulic breaker E, its mounting hole E1 extends to one side, so the hydraulic breaker E will not interfere with the first cylinder 15. For a specific structural diagram after connection, please refer to [reference needed]. Figure 9 It should also be noted that the connection of the hydraulic breaker E requires the use of an external pin E2. That is, after the mounting hole and the connection hole 231 of the hydraulic breaker E are aligned, the hydraulic breaker E is locked onto the connecting frame 2 by passing the pin E2 through it. Since the first cylinder 15 is not needed for fixing, the oil pipe that drives the first cylinder 15 can be installed on the hydraulic breaker E for use by the hydraulic breaker E.

[0044] Example 2

[0045] refer to Figures 4-10 A support vehicle includes a vehicle body 3, a boom 31, a swing arm 32, a tie rod 33, and the boom mechanism of Embodiment 1. The vehicle body 3 is provided with a first drive unit 34 and a second drive unit 34. The boom 31 is hinged to the vehicle body 3. The power output end 151 of the first drive unit 34 is hinged to the boom 31, and the end of the boom 31 is hinged to the boom 31 connecting part 11. The first drive unit 34 is used to drive the boom 31 to swing. The middle part of the swing arm 32 is hinged to the middle part of the boom 31. The output end 151 of the second drive unit 34 is hinged to one end of the boom 31, and the other end of the boom 31 is hinged to the tie rod 33. The end of the tie rod 33 is hinged to the tie rod 33 connecting part 21.

[0046] Specifically, the first drive unit 34 is the second hydraulic cylinder, and the second drive unit 34 is the third hydraulic cylinder. Implicitly, a power supply module and an oil supply module are also provided on the vehicle body 3. The oil supply module mainly supplies oil to the first hydraulic cylinder 15, the second hydraulic cylinder, and the third hydraulic cylinder. It should be noted that if the first connecting part 12 is connected to the sweeping roller assembly B mentioned in Embodiment 1, then the drive motor B2 of the sweeping roller assembly B needs to be connected to the power supply module; if the first connecting part 12 is connected to the bucket A with clamping function mentioned in Embodiment 1, then the clamping drive cylinder needs to be connected to the oil supply module; if the second connecting part 22 is connected to the hydraulic breaker E, then the oil supply line of the first hydraulic cylinder 15 is replaced in the hydraulic breaker E.

[0047] Preferably, the boom 31 includes a left arm 311, a right arm 312, and a connecting column 313. The left arm 311 and the right arm 312 are both hinged to the vehicle body 3. The two ends of the connecting column 313 are connected to the left arm 311 and the right arm 312 respectively. The middle part of the swing arm 32 is hinged to the middle part of the connecting column 313. There are two first drive units 34, which are hinged to the left arm 311 and the right arm 312 respectively.

[0048] In practical use, the left arm 311 and right arm 312 move synchronously under the connection of the connecting column 313, which is used to drive the bracket 1 and the connecting frame 2 to swing up and down around the vehicle body 3. The function of the swing arm 32 is to drive the bracket 1 and the connecting frame 2 to swing around the end of the boom 31, mainly for adjusting the working angle of the first or second functional accessory. The boom 31, swing arm 32, and tie rod 33 are all prior art in this field. For the specific structure, please refer to the technical solution of Chinese Patent CN111877446A. Therefore, the specific details and working methods of the boom 31, swing arm 32, and tie rod 33 will not be described in detail in this embodiment.

[0049] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
