Description

Technical Field

[0001] This application belongs to the field of engineering machinery technology, specifically relating to a protective cover for a tower crane brake and a tower crane. Background Technology

[0002] In the field of construction machinery, construction equipment often faces complex operating conditions such as flying rocks, tree branches, and dust, thus requiring the installation of protective devices on the exterior of critical mechanisms. Taking the brake of the hoisting mechanism of a tower crane as an example, such as... Figure 1 As shown, the currently commonly used semi-enclosed integrated protective cover (10) is mainly composed of a bracket (11), a cover body (12), and a handle (13), and is installed on the base of the brake (20) through the bracket (11). This integrated protective cover (10) must be hoisted and disassembled as a whole during maintenance. Due to the limited space on the side of the brake (20), the disassembly and assembly operations are extremely difficult, which is not only time-consuming and labor-intensive, but also significantly reduces the operation and maintenance efficiency of the equipment. Utility Model Content

[0003] The purpose of this application is to provide a tower crane brake protective cover and a tower crane, in order to solve the problems of existing integrated protective covers, which are difficult to disassemble and assemble, time-consuming and labor-intensive, and have low operation and maintenance efficiency.

[0004] To achieve the above objectives, a first aspect of this application provides a protective cover for a tower crane brake, comprising: The main cover includes a mounting base and a cover body disposed on the mounting base. A first accommodating space is formed inside the cover body. The top of the cover body and along its width direction are provided with protective cover plates, and open rear inspection ports and front inspection ports are respectively formed at both ends along its length direction. The surface where the rear inspection port is located is a slope. The rear inspection cover has a second accommodating space inside. The rear inspection cover is detachably installed on the cover body to correspond to the rear inspection port. The rear inspection cover is used to cover the rear inspection port and has a docking opening on the side facing the cover body that matches the rear inspection port. When the rear inspection cover covers the rear inspection port, the second accommodating space and the first accommodating space communicate to form a semi-enclosed protective space.

[0005] As a further improvement to the above technical solution: In some embodiments, one end of the rear maintenance cover is hinged to the mounting base, and the other end is detachably connected to the protective cover plate located at the top of the cover body via a first locking assembly; or, one end of the rear maintenance cover is hinged to the protective cover plate located at the top of the cover body, and the other end is detachably connected to the mounting base via a first locking assembly.

[0006] In some embodiments, a first top joint is formed between the rear inspection cover and the protective cover plate located at the top of the cover body, and the protective cover is provided with a first waterproof structure corresponding to the first top joint. The first waterproof structure includes a first water guide channel, which is disposed inside the cover body. One side of the first water guide channel is disposed on the protective cover plate located at the top of the cover body, and the other side of the first water guide channel extends through the first top joint. Both ends of the first water guide channel extend along the width direction of the cover body and are welded to the protective cover plate on the corresponding side. Among them, at least one of the protective cover plates located in the width direction of the cover body is provided with a first drain hole that communicates with the first water guide groove.

[0007] In some embodiments, the cross-sectional shape of the first water guide channel along its width direction is U-shaped or V-shaped; The wall of the first drain hole is aligned with the bottom of the first water guide channel.

[0008] In some embodiments, the docking opening is provided with a cover plate portion extending away from the rear maintenance cover on both sides along its own width direction. The width between the outer surfaces of the cover plate portions on both sides of the docking opening along its own width direction is defined as W1, and the width between the outer surfaces of the protective cover plates on both sides of the cover body along its own width direction is defined as W2, where W1≥W2. When the rear inspection cover covers the rear inspection port, the cover plate overlaps with the corresponding protective cover plate.

[0009] In some embodiments, the tower crane brake guard further includes a front inspection cover, which has a third accommodating space. The front inspection cover is detachably mounted on the cover and arranged on the side opposite to the front inspection port. When the front inspection cover covers the front inspection port, the third accommodating space is connected to the first accommodating space.

[0010] In some embodiments, the top of the front inspection cover is hinged to the protective cover plate located at the top of the cover body, and the two sides of the front inspection cover are detachably connected to the protective cover plates located on the sides of the cover body via a second locking assembly.

[0011] In some embodiments, a second top joint is formed between the front inspection cover and the protective cover plate located at the top of the cover body, and the protective cover is provided with a second waterproof structure corresponding to the second top joint. The second waterproof structure includes a second water guide channel, which is disposed inside the cover body. One side of the second water guide channel is disposed on the protective cover plate located at the top of the cover body, and the other side of the second water guide channel extends through the second top joint seam. The mounting base includes a front support beam, which is arranged corresponding to the front inspection port and located in the first accommodating space. The upper end of the front support beam abuts against the second water guide trough cover, and the lower end extends along the height direction of the cover body to the outside of the first accommodating space. The front support leg beam has a drainage channel inside, and the bottom of the second water guide trough has a second drainage hole in the area overlapping with the upper end of the support leg beam. The second drainage hole is connected to the drainage channel.

[0012] In some embodiments, the top of the front inspection cover is provided with a cover plate, and the two sides of the cover plate form an outwardly convex rainproof eave structure along the width direction of the front inspection cover.

[0013] To achieve the above objectives, the second aspect of this application also provides a tower crane, including a tower crane brake guard according to the first aspect.

[0014] Compared to existing technologies, the tower crane brake guard and tower crane provided in this application have at least the following beneficial effects: The tower crane brake protective cover provided in this application adopts a modular design consisting of a main cover and a rear maintenance cover. The main cover is installed via a mounting base and supported by the mounting base. The cover has open rear and front maintenance openings at both ends along its length. The rear maintenance cover covers the rear maintenance opening and has a mating opening on the side facing the cover that matches the rear maintenance opening. When the rear maintenance cover covers the rear maintenance opening, the second accommodating space connects with the first accommodating space to form a semi-enclosed protective space to protect the tower crane brake. Thus, when the brake requires maintenance, it is not necessary to remove the entire protective cover; only the rear maintenance cover needs to be disassembled to expose the rear maintenance opening, allowing for maintenance and repair through the rear maintenance opening. This design makes efficient use of space, simplifies operation, and greatly improves the efficiency of equipment operation and maintenance.

[0015] In addition, the surface where the rear inspection port is located is a slope. The slope design follows ergonomics to facilitate subsequent inspection and maintenance operations, making operation more convenient, further reducing manual labor fatigue, and improving efficiency.

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0021] Example Please see Figure 2 and Figure 3 This embodiment provides a protective cover for a tower crane brake (hereinafter referred to as the protective cover 100), and more particularly provides a protective cover for the main brake of the hoisting mechanism of a tower crane. The tower crane brake protective cover 100 can be used to protect the brakes of a tower crane (such as...) Figure 1 The brake (as shown in label 20) is used for protection to ensure the normal and stable operation of the equipment.

[0022] The tower crane brake protective cover 100 provided in this embodiment is hereinafter referred to as the protective cover 100. The protective cover 100 includes a main cover 110 and a rear maintenance cover 120.

[0023] The main cover 110 includes a mounting base 111 and a cover body 112 disposed on the mounting base 111. The mounting base 111 can be connected to the base of the brake via fasteners, thereby providing effective support for the cover body 112. This embodiment... Figure 1 , Figure 4 and Figure 5The direction indicated by arrow L in the diagram is consistent with the length direction of the cover body 112, and the direction indicated by arrow W is consistent with the width direction of the cover body 112. Under normal use, the main cover body 110 is installed vertically.

[0024] In this embodiment, a first accommodating space 112a is formed inside the cover body 112. The top of the cover body 112 and along its own width direction are provided with protective cover plates 1122, and open rear inspection port 1120 and front inspection port 1121 are respectively formed at both ends along its own length direction. The surface where the rear inspection port 1120 is located is a slope.

[0025] The rear inspection cover 120 has a second accommodating space 120a inside. The rear inspection cover 120 is detachably installed on the cover body 112 to correspond to the rear inspection port 1120. The rear inspection cover 120 is used to cover the rear inspection port 1120 and has a docking opening 121 on the side facing the cover body 112 that matches the rear inspection port 1120.

[0026] When the rear inspection cover 120 covers the rear inspection port 1120, the second accommodating space 120a and the first accommodating space 112a are connected to form a semi-enclosed protective space 100a. At this time, the semi-enclosed protective space 100a can provide effective protection for the brake.

[0027] Thus, when the brake requires inspection and maintenance, it is not necessary to remove the entire protective cover 100 (nor to disassemble the connection between the mounting base 111 on the main cover 110 and the brake base). Only the rear inspection cover 120 needs to be disassembled to expose the rear inspection port 1120, allowing for inspection and maintenance through the rear inspection port 1120. This makes efficient use of space, simplifies operation, and greatly improves the efficiency of equipment operation and maintenance. Similarly, equipment problems located at the front inspection port 1121 can be inspected through the front inspection port 1121 without disassembling the connection between the mounting base 111 and the brake base.

[0028] In addition, the surface where the rear inspection port 1120 is located is a slope. The slope design is more in line with the ergonomic principle, which makes it easier to carry out subsequent inspection and maintenance operations, making the operation more convenient, further reducing manual labor fatigue and improving efficiency.

[0029] Optionally, the angle between the plane containing the rear access port 1120 and the top plane of the cover 112 is 45°±20°. This angle design follows ergonomics, reducing operator fatigue; on the other hand, it provides a wider operating area and better field of vision.

[0030] In some embodiments, handles 1123 may be provided on the protective cover plates 1122 on both sides of the cover body 112 (e.g., handles 1123). Figure 2 and Figure 3 (as shown) or lugs, to facilitate assembly and transport.

[0031] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, one end of the rear access cover 120 is hinged to the mounting base 111, specifically through a first hinge assembly 140. A hinge mounting plate 1114 for mounting the first hinge assembly 140 can be provided on the mounting base 111, thus enabling the rear access cover 120 to be flipped downwards and opened. Optionally, the first hinge assembly 140 can be a hinge or a hinge hinge mechanism.

[0032] The other end of the rear inspection cover 120 is detachably connected to the protective cover 1122 located on top of the cover body 112 via the first locking assembly 130. The first locking assembly 130 is a quick-release assembly, such as a locking pin assembly, a buckle assembly 130a, or a magnetic assembly.

[0033] Understandably, when a locking pin assembly is used to achieve a detachable connection between the rear inspection cover 120 and the corresponding protective cover 1122, a first locking pin portion with a first pin hole is provided at the top of the rear inspection cover 120, and a second locking pin portion with a second locking pin hole is provided on the protective cover 1122 located at the top of the cover 112. Then, a locking pin shaft is arranged through the first and second pin holes to connect the first and second locking pin portions. The rear inspection cover 120 and the cover 112 can be quickly assembled and disassembled simply by inserting and removing the locking pin shaft, thus improving operational efficiency. Figure 4 and Figure 6 As shown, when using the latch assembly 130a, a latch hook 131 can be provided on the top of the rear access cover 120, and a latch lock body 132 can be provided on the protective cover plate 1122 at the top of the cover body 112. The latch lock body 132 and the latch hook 131 cooperate to achieve quick assembly and disassembly of the rear access cover 120 and the cover body 112. When using the magnetic assembly, magnetic components can be provided on both the access cover 12 and the cover body 112. The magnetic attraction of the magnetic components can achieve quick assembly and disassembly of the rear access cover 120 and the cover body 112.

[0034] It should be noted that the above description of the first locking component 130 is merely illustrative and should not be construed as limiting the scope of protection of this application.

[0035] In some embodiments, one end of the rear access cover 120 is hinged to the protective cover 1122 at the top of the cover body 112, and the other end is detachably connected to the mounting base 111 via the first locking assembly 130. This allows the rear access cover 120 to be flipped upwards and opened. The first locking assembly 130 can adopt the structure described above, and will not be repeated here.

[0036] Please refer to the following: Figure 6 and Figure 7 Furthermore, a first top joint S1 is formed between the rear inspection cover 120 and the top protective cover 1122 of the cover body 112. The protective cover 100 is provided with a first waterproof structure corresponding to the first top joint S1 to prevent rainwater from entering the brake from the first top joint S1.

[0037] Specifically, the first waterproof structure includes a first water guide channel 123, which is disposed inside the cover body 112. One side of the first water guide channel 123 is disposed on the protective cover plate 1122 located at the top of the cover body 112. The first water guide channel 123 and the protective cover plate 1122 can be connected by welding, screw bolts, or riveting. The other side of the first water guide channel 123 extends through the first top joint S1. Both ends of the first water guide channel 123 extend along the width direction of the cover body 112 and are welded to the corresponding protective cover plates 1122 (the protective cover plates 1122 located on both sides of the cover body 112). During welding, the gap between the first water guide channel 123 and the corresponding protective cover plate 1122 is filled to prevent water from seeping out through the gap and protect the equipment safety.

[0038] Please see Figure 2 and Figure 6 The protective cover plate 1122 located in the width direction of the cover body 112 is provided with a first drain hole 124 communicating with the first water guide groove 123. The height of the other side of the first water guide groove 123 is higher than the hole wall of the first drain hole 124 near the bottom of the first water guide groove 123. In this way, water entering from the first top joint S1 will collect in the first water guide groove 123 and then be discharged from the first water guide groove 123 through the first drain hole 124, thereby effectively preventing water from entering the brake, protecting the equipment from corrosion, and extending its service life.

[0039] Optionally, the cross-sectional shape of the first water guide trough 123 along its width direction is U-shaped or V-shaped, or other shapes can be used, as long as the function of water collection is met.

[0040] In some embodiments, the wall of the first drain hole 124 is aligned with the bottom of the first water guide channel 123 so that the water entering the first water guide channel 123 can be discharged quickly and smoothly.

[0041] Please see Figure 5 and Figure 7In this embodiment, the docking opening 121 has cover plate portions 122 extending away from the rear maintenance cover 120 on both sides along its width direction. The width between the outer surfaces of the cover plate portions 122 on both sides of the docking opening 121 along its width direction is defined as W1, and the width between the outer surfaces of the protective cover plates 1122 on both sides of the cover body 112 along its width direction is defined as W2, where W1 ≥ W2. When the rear maintenance cover 120 covers the rear maintenance opening 1120, the cover plate portions 122 overlap with the corresponding protective cover plates 1122 on both sides of the cover body 112. Thus, the "overlapping waterproof joint" scheme achieves waterproofing of the side joint between the cover body 112 and the rear maintenance cover 120. This structure can effectively prevent vertical splashing water and dust from directly intruding into the side joint.

[0042] In some embodiments, when the gap between the cover plate portion 122 and the corresponding protective cover plate 1122 is large, a seal may be provided between the cover plate portion 122 and the corresponding protective cover plate 1122. The seal may be provided on the inner surface of the cover plate portion 122 or on the outer surface of the protective cover plate 1122.

[0043] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The protective cover 100 also includes a front inspection cover 150, which has a third accommodating space. The front inspection cover 150 is detachably mounted on the cover body 112 and arranged on the side opposite to the front inspection port 1121. When the front inspection cover 150 covers the front inspection port 1121, the third accommodating space communicates with the first accommodating space 112a. In this way, the front inspection cover 150 can form an extended brim structure to achieve protection for the components located at the front end of the brake.

[0044] The top of the front inspection cover 150 is hinged to the protective cover 1122 located on the top of the cover body 112, and the two sides of the front inspection cover 150 are respectively detachably connected to the protective cover 1122 located on the sides of the cover body 112 via the second locking assembly 170.

[0045] The top of the front inspection cover 150 is hinged to the protective cover 1122 at the top of the cover body 112 via a second hinge assembly 160. The second hinge assembly 160 can be a hinge or a hinge, thus enabling the front inspection cover 150 to be opened upwards. In this embodiment, the structure of the second locking assembly 170 can be the same as that of the first locking assembly 130 described above, and will not be repeated here.

[0046] Please refer to the following: Figure 5 , Figure 8 and Figure 9Furthermore, a second top joint S2 is formed between the front inspection cover 150 and the cover body 112 at the top protective cover plate 1122. The protective cover 100 is provided with a second waterproof structure corresponding to the second top joint S2. In this way, the second waterproof structure achieves waterproofing between the front inspection cover 150 and the cover body 112, preventing rainwater from entering the brake from the second top joint S2.

[0047] The second waterproof structure includes a second water guide channel 125, which is disposed within the cover body 112. One side of the second water guide channel 125 is disposed on the protective cover plate 1122 located at the top of the cover body 112. Specifically, the second water guide channel 125 and the protective cover plate 1122 can be connected by welding, screw bolts, or riveting. The other side of the second water guide channel 125 extends through the second top joint S2.

[0048] Optionally, the cross-sectional shape of the second water guide trough 125 along its width direction is U-shaped or V-shaped, or other shapes can be used, as long as the function of water collection is met.

[0049] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the mounting base 111 is a truss structure, comprising a front support beam 1110 and a rear support beam 1111. The front support beam 1110 is arranged corresponding to the front access port 1121 and located in the first accommodating space 112a. The upper end of the front support beam 1110 abuts against the second water guide trough 125 cover, and the lower end extends along the height direction of the cover body 112 to the outside of the first accommodating space 112a. The rear support beam 1111 is arranged corresponding to the rear access port 1120. A support base plate 1112 is provided at the end of both the front and rear support beams away from the cover body 112. The support base plate 1112 has mounting holes for fasteners. The fasteners can be screws or bolts.

[0050] Please see Figure 4 , Figure 8 and Figure 9 The front outrigger beam 1110 and the rear outrigger beam 1111 each have two sections. The front outrigger beam 1110 has an internal drainage channel 1113. The bottom of the second water guide groove 125 has a second drainage hole 1250 in the area overlapping with the upper end of the outrigger beam. The second drainage hole 1250 communicates with the drainage channel 1113. Thus, after water enters the second water guide groove 125, it can directly enter the drainage channel 1113 inside the front outrigger beam 1110 through the second drainage hole 1250, and then be discharged along the drainage channel 1113, preventing water from entering the brake.

[0051] Optionally, the front outrigger beam 1110 is made of channel steel, square steel, or round tubing. The channel steel, square steel, or round tubing forms a hollow cavity, which serves as a drainage channel 1113. A third drainage hole is then provided on the outward-facing side of the bottom of the front outrigger beam 1110 for drainage, preventing water from accumulating in the drainage channel 1113. When channel steel is used, the cross-section of the front outrigger beam 1110 in the width direction is U-shaped. During design, it is ensured that the channel opening faces outward (towards the side opposite the brake) to facilitate water drainage to the outside of the brake.

[0052] Please see Figure 4 , Figure 5 and Figure 9 In this embodiment, the top of the front inspection cover 150 is provided with a cover plate 151, and the two sides of the front inspection cover 150 are also provided with side plates. The side plates and the cover plate 151 surround each other to form a third accommodating space. Along the width direction of the front inspection cover 150, the two sides of the cover plate 151 protrude outward to form an outwardly protruding rainproof eaves structure 1510.

[0053] Specifically, on the side near the front inspection port 1121, the sides of the protective covers 1122 on both sides of the cover 112 protrude a certain distance compared to the side of the protective cover 1122 on the top. This causes the sides of the front inspection cover 150 to shrink inward by the same distance, so that after the front inspection cover 150 and the cover 112 are assembled, the second top joint S2 on the top is misaligned with the joints on both sides. In this way, the outwardly protruding rainproof eaves structure 1510 can block rainwater from the joints on the sides of the front inspection cover 150, preventing rainwater from entering from the top.

[0054] Please see Figures 1 to 9 Furthermore, this embodiment also provides a tower crane. The tower crane includes a brake assembly and a protective cover 100 according to the above embodiment. The protective cover 100 is disposed on the brake assembly and is used to protect the brake.

[0055] The protective cover 100 provided in this embodiment, through its modular split structure and systematic waterproof and drainage design, completely solves the problems of traditional integrated brake covers (such as...). Figure 1 The fundamental pain points (as shown) have been addressed, and maintainability, protection, and security have been improved simultaneously.

[0056] The core advantages and disadvantages of this embodiment compared with the prior art are as follows: Existing technology (integral semi-enclosed protective cover): Maintainability: Extremely poor; requires complete disassembly; operation is complex, time-consuming, labor-intensive, and requires the assistance of lifting equipment. Inspection capability: Generally, only the portion below the center line of the brake pads can be observed; Heat dissipation: Average; Safety: Disassembly is high-risk. When repairing the brake, the entire protective cover is disassembled, which is complicated and prone to risks such as collisions during hoisting and personnel miscoordination.

[0057] This embodiment's solution (a modular protective cover): Maintainability: Excellent; can be partially opened to provide precise inspection channels; no need for complete disassembly; can be quickly operated by a single person. Inspectionability: Excellent; the front and rear access doors increase the daily inspection view. Heat dissipation: Good. The module seams and drainage holes objectively promote airflow, which is beneficial for heat dissipation. Safety: Low operational risk, partial opening, clear maintenance objectives, simple and safe operation, significantly reducing secondary risks during maintenance.

[0058] Furthermore, the tower crane provided in this embodiment has the following advantages and economic benefits: 1. Significantly improves maintenance efficiency and reduces maintenance costs. Results: Maintenance work that previously required hours and multiple people can now be completed in minutes by a single person. This significantly reduces equipment downtime and improves the effective working hours and utilization rate of the tower crane.

[0059] Economic benefits: It saves a lot of labor costs and equipment (crane) usage costs, and significantly reduces overall maintenance costs.

[0060] 2. Implement preventative maintenance to improve equipment reliability. Effect: The convenient inspection function enables maintenance personnel to regularly and quickly check the wear condition of the brakes and whether there is any oil leakage, so as to detect the fault in the early stage and avoid serious accidents (such as heavy objects falling) caused by sudden brake failure.

[0061] Economic efficiency: The cost of replacing wear parts such as friction plates in a planned manner is far lower than the huge losses caused by emergency repairs, component damage, or even production interruption after a failure occurs.

[0062] 3. Enhance environmental adaptability and extend component lifespan. Effect: The unique active drainage design ensures the protective performance of the cover under harsh conditions such as rain, snow, and moisture, effectively preventing water accumulation, ice formation, or corrosion inside the brake and ensuring its operational reliability.

[0063] Economic benefits: It reduces the corrosion of precision components such as brake discs, friction pads, and levers by moisture and impurities, extends the service life of the brake assembly, and reduces the frequency of spare parts replacement.

[0064] 4.
