Problems solved by technology

The disadvantage of this structure is that the stroke of the oil cylinder is too long, and the frequent telescopic movement of the oil cylinder will easily cause the seal of the oil cylinder to be damaged and cause oil leakage.
In addition, the above-mentioned safety doors all have the problems of heavy weight, high failure rate, poor effect of blocking heavy vehicles, complex structure, and inconvenient maintenance.

Embodiment 1

[0016] Embodiment one: figure 1 , 2 As shown in and 3, it is mainly composed of a column, double raceways, pin row 5, roller group 6, door body 7, bracket 8, pin gear 13 and hydraulic motor 14, and a transmission composed of pin gear 13 and hydraulic motor 14 is adopted. The mechanism drives the hydraulic motor 14 through the hydraulic transmission system, the hydraulic motor 14 directly drives the pin gear 13, and the pin gear 13 drives the pin row 5 to make the door body 7 translate; there are two door bodies 7, and each door body controls the entry of a cage. Each door body is driven by a corresponding drive mechanism to move left and right in an open raceway. Two rows of open raceways are arranged side by side on three parallel columns, and each row of open raceways is formed by two channel steel mouth-to-mouth intervals. The columns are divided into left column 1, middle column 15 and right column 11; The open raceway is formed by the docking of the left raceway 4 and t...

Embodiment

[0017] The second embodiment: Figure 4 , Figure 5 with Image 6 As shown, it is basically the same as Embodiment 1, the difference is only in the arrangement of the hydraulic motor 14, the pin gear 13 and the pin row 5, and the two pin rows 5 are horizontally arranged above the open raceway, respectively placed by two channel steel On the left and right raceways 4 and 9 that are formed by pairing, directly mesh with the pin gear 13, and two roller groups 6 connected with the door body 7 are installed under each pin row 5; The engaged pin gear 13 is arranged vertically, and the hydraulic motor 14 is arranged horizontally. The roller set 6 is still rolling in the left raceway 4 and the right raceway 9, the hydraulic motor 14 drives the pin gear 13, and the pin gear 13 drives the pin row 5 to move horizontally, and the pin row 5 brings the door body 7 to open or close.

Abstract

The automatic hydraulic horizontally shifted safety door is especially suitable for use in the entrance of hoisting cage in vertical well of coal mine. It consists of two door bodies and each door body controls one entrance of the hoisting cage through the horizontal shifting along one opened roller track under the driving of the driving mechanism. The opened roller track is set on three parallel uprights, and consists of right roller track and left roller track for roller combination to roll in, with the roller combination and stud rank being connected to the door body integrally. The transmission mechanism has hydraulic motor driving stud wheel directly and the stud wheel drives the stud rank, and the transmission system is simple, great in bearing capacity and smooth in running. The right roller track may be opened for loading long material. The whole system is safe, reliable, simple in structure, light, convenient and widely applicable.

Description

technical field [0001] The invention relates to a hydraulic translational automatic safety door, which is especially suitable for the entrance and exit of the hoisting cage of the coal mine vertical shaft. Background technique [0002] In the coal mine shaft lifting mode, when the lifting container cage is running or not parked in place, it is necessary to use the safety door to protect the upper and lower wellheads, so as to prevent people, mine cars or other objects from accidentally falling into the shaft, causing undue personnel and property loss. At present, most mine safety doors are powered and cannot be opened at will. There are many types of power safety doors, of which there are two commonly used ones: one is pneumatic or hydraulic sliding safety doors, the door body of the safety door uses sliding, and an air cylinder or hydraulic cylinder is used to connect one end of the slideway, and the other end is fixed. The door body slide...
