[0029] Example:

[0030] like Figures 1-4 As shown, the present invention provides a wheel-side self-locking two-in-one brake, comprising a wheel-side brake bracket 1, the upper portion of the wheel-side brake bracket 1 being connected to the wheel-side brake by bolts, and the lower portion being connected to the windproof iron wedge brake by bolts.

[0031] The present invention innovatively integrates the wheel brake and the windproof iron wedge brake together by means of the wheel brake bracket 1, thereby ultimately having the characteristics of high intelligence, easy use, simple structure and high braking efficiency.

[0032] Specifically,

[0033] The wheel brake comprises a wheel power cylinder 2 , a pushing device 3 driven and controlled by the wheel power cylinder 2 , and two oppositely arranged wheel brake arms 4 connected to the pushing device 3 .

[0034] The windproof iron wedge brake includes an iron wedge power cylinder 5, an iron wedge plate 6 driven by the iron wedge power cylinder 5 to perform telescopic movement, and an iron wedge self-locking device 7 rotatably connected to the end of the iron wedge plate 6 away from the iron wedge power cylinder 5.

[0035] When the power sources of the wheel side power cylinder 2 and the iron wedge power cylinder 5 are disconnected, the wheel side brake arm 4 clamps the wheel while the iron wedge self-locking device 7 also wedges the wheel, forming double braking.

[0036] The wheel brake structure used in the present invention belongs to the existing technology. Its specific working principle can be referred to the invention patent application with application publication number CN113833781A or other existing structural designs that can achieve wheel brake, which will not be described in detail here.

[0037] Furthermore, if Figure 5-Figure 8 As shown, the windproof iron wedge brake of the present invention includes an iron wedge power cylinder 5, an iron wedge plate 6, an iron wedge self-locking device 7, an iron wedge support plate 8, an iron wedge stroke device 9 and an iron wedge push rod 10. The two iron wedge support plates 8 are vertically installed on the lower part of the wheel brake bracket 1 by bolts and are arranged in parallel; an iron wedge stroke device 9 is correspondingly installed on the inner plate surface of each iron wedge support plate 8, and the two iron wedge stroke devices 9 are arranged opposite to each other, and corresponding iron wedge stroke guide holes 11 are opened on the two iron wedge stroke devices 9; the iron wedge plate 6 is located between the two iron wedge stroke devices 9, and the stroke shaft fixed on the iron wedge plate 6 12 is inserted into the iron wedge stroke guide holes 11 on both sides, so that the iron wedge plate 6 is connected to the iron wedge stroke device 9 and can also move along the iron wedge stroke guide holes 11; the iron wedge power cylinder 5 is installed on the upper position of the iron wedge support plate 8 by bolts, and the output end of the iron wedge power cylinder 5 is downwardly connected to the iron wedge push rod 10, and the other end of the iron wedge push rod 10 is connected to the upper end of the iron wedge plate 6 through a pin shaft. The direction of the iron wedge stroke guide hole 11 is consistent with the telescopic direction of the iron wedge push rod 10. The iron wedge power cylinder 5 is powered by the iron wedge push rod 10, and controls the rise and fall of the iron wedge plate 6 through the iron wedge stroke device 9.

[0038] The lower end of the iron wedge plate 6 is the braking end, which is used to rotate and connect the iron wedge self-locking device 7. When the iron wedge power cylinder 5 is connected to the power source, the iron wedge plate 6 is controlled to rise. When the power source is disconnected, the iron wedge plate 6 falls under the action of gravity, and the iron wedge self-locking device 7 wedges the wheel.

[0039] At the same time, a fixed support plate 13 can be installed on the iron wedge plate 6 near one end of the iron wedge self-locking device 7. The fixed support plate 13 is connected with a manual adjustment bolt 14 and a spring 15 sleeved on the manual adjustment bolt 14. The manual adjustment bolt 14 can support the iron wedge self-locking device 7 by adjustment; when the power source of the iron wedge power cylinder 5 is disconnected, the iron wedge plate 6 drops under the action of gravity, and at the same time, under the action of the telescopic force of the spring 15, the iron wedge self-locking device 7 weds the wheel.

[0040] The iron wedge self-locking device 7 of the present invention is specifically a wedge block rotatably connected to the braking end of the iron wedge plate 6 through a pin shaft, and the upper part of the wedge block is an inner arc surface matching the outer cylindrical surface of the wheel.

[0041] The working principle of the windproof iron wedge brake in the present invention also belongs to the existing technology, and its structural design is not limited to the above-mentioned structural design. Any windproof iron wedge brake that can achieve the corresponding wedge-type windproof braking effect is within the protection scope of the present invention.

[0042] The present invention further installs an intelligent sensing system on the wheel-side brake bracket 1 through a bolt connection. The remote control system located at the far end is communicated with the intelligent sensing system. The intelligent sensing system includes a sensor switch 16 for controlling and sensing the opening and closing of the wheel-side power cylinder 2 and the iron wedge power cylinder 5.

[0043] Furthermore, the intelligent sensing system also includes sensors that can measure the operating temperature and braking force of the wheel-side brakes and windproof iron wedge brakes, as well as corresponding data display devices, to realize the display of intelligent temperature, braking force and travel data.

[0044] In the present invention, the wheel-side power cylinder 2 and the iron wedge power cylinder 5 can each be connected to an independent power source, or they can share a common power source. The power source can be any one of a hydraulic power source, an electro-hydraulic power source, and an electromagnetic suction power source. In other words, the hydraulic power source, the electro-hydraulic power source, and the electromagnetic suction power source can each be used independently or in combination as the power source for the wheel-side self-locking two-in-one brake.

[0045] More specifically, the hydraulic power source is installed on the outside of the wheel-side brake bracket 1 through a hydraulic pipeline, and the motor hydraulic power source and the electromagnetic suction power source are installed on the connecting bracket of the wheel-side brake bracket 1.

[0046] The wheel side brake and windproof iron wedge brake in the present invention realize the wheel side self-locking dual braking function through hydraulic power source, motor hydraulic power source and electromagnetic suction power source independently or in combination, thereby reducing the power source, simplifying the structure and improving space utilization.

[0047] Working process:

[0048] When the wheel-side self-locking two-in-one brake of the present invention is connected to the power source, the power drives the wheel-side brake arm 4 and the iron wedge self-locking device 7 thereon to release the brake through the wheel-side power cylinder 2 and the iron wedge power cylinder 5; after the power source is disconnected, the wheel-side brake arm 4 and the iron wedge self-locking device 7 perform a braking action, realizing wheel-side self-locking dual braking, thereby realizing a two-in-one braking function, improving space utilization while also improving work efficiency, and improving the windproof effect and safety factor of the brake.

[0049] At the same time, in order to further improve the level of intelligence, the present invention is also provided with a remote control system, which provides an interface through the intelligent sensing system to realize remote control of the wheel-side power cylinder 2 and the iron wedge power cylinder 5, and drive the wheel-side brake arm 4 and the iron wedge self-locking device 7 to realize wheel-side self-locking double braking. There is no need for workers to perform operations outdoors, and production efficiency is further improved.
