[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] In the description of this specification, reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the utility model. In the utility model, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0028] refer to Figure 1-Figure 2The present embodiment provides a flying chair blocking device for an overhead passenger device, which includes a fixed seat 3; a trigger mechanism located on the fixed seat 3 and a baffle 4 that can move in the length direction of a vertical steel wire rope 8. The fixed seat 3 is used to fix the chair blocking device on the steel beam at the top of the coal mine tunnel. The trigger mechanism is installed on a mounting plate on the fixed seat 3. The baffle 4 is movably installed on the fixed seat 3 and can move in the length direction of the vertical steel wire rope 8.

[0029] In a possible embodiment, the trigger mechanism includes a push rod mechanism 1 and a locking device controlled by the push rod mechanism 1, and the locking device is used to lock the baffle 4 at a first set height above the wire rope 8. The first height refers to the height at which the baffle 4 does not hinder the normal passage of the rope gripper, that is, when the overhead passenger device is in normal passage, the baffle 4 is in a normally open state.

[0030] The push rod mechanism 1 is configured to control the locking device to release the lock of the baffle 4 when receiving the control signal, so that the baffle 4 moves to the second set height above the wire rope 8 under the action of gravity, and the moving direction is as follows: Figure 2 The control signal here refers to the signal that triggers the push rod mechanism 1 to respond, and the response signal comes from the speed signal of the wire rope 8. When the speed signal exceeds the set value, the push rod mechanism 1 starts. The control module of the push rod mechanism 1 here is electrically connected to the control box of the overhead passenger device.

[0031] This embodiment receives the running speed signal of the overhead passenger device. When the running speed exceeds the set value, the push rod mechanism 1 is controlled to act, and the push rod mechanism 1 controls the locking device to unlock the baffle 4. The unlocked baffle 4 automatically falls above the wire rope 8 under the action of gravity, thereby blocking the wire rope gripper.

[0032] refer to Figure 2 and Figure 3 In some possible embodiments, the locking device includes a locking member 7, and a locking slot 41 is provided on the upper part of the baffle 4. The locking member 7 is locked in the locking slot 41 when the running speed of the overhead passenger device does not exceed the set speed threshold; when the overhead passenger device reaches or exceeds the set threshold, the pushing rod mechanism 1 controls the locking member 7 to move out of the locking slot 41, thereby unlocking the locking device.

[0033] refer to Figure 4In some embodiments, the clamping member 7 is configured as a hook-shaped structure, which includes a rod 73 and a hook 72. The rod 73 of the hook-shaped structure is connected to the fixing seat 3 through an elastic member 2, and the end of the extension rod 11 of the push rod mechanism 1 abuts against the rod 73. The elastic member 2 here is used to press the rod 73 against the end of the extension rod 11; the middle part of the hook-shaped structure is hinged on the fixing seat 3, and the hook 72 here is used to snap into the slot 41. In other words, the push rod mechanism 1 acts on the clamping member 7 to rotate the clamping member 7 around the hinge point, and the clamping member 7 after rotation is reset by the elastic member 2. The elastic member 2 here can also keep the rod 73 pressed against the end of the extension rod 11 to prevent the clamping member 7 from shaking and enhance the stability of the structure.

[0034] Continue to refer Figure 4 Furthermore, a groove 71 is provided on a side of the rod portion 73 facing the extension rod 11 , and an end portion of the extension rod 11 is arranged in the groove 71 .

[0035] refer to Figure 1 and Figure 2 Furthermore, a side of the top of the baffle plate 4 facing the hook portion 72 is chamfered or rounded. When the baffle plate 4 needs to be reset, the baffle plate 4 only needs to be pushed up, and the chamfered or rounded corner on the baffle plate 4 cuts into the bottom of the hook portion 72 of the locking member 7. Under the action of the elastic member 2, the hook portion 72 of the locking member 7 is automatically locked into the locking groove 41.

[0036] In some possible embodiments, the elastic member 2 is configured as a tension spring. Two ends of the tension spring are respectively connected to the upper end of the locking member 7 and the fixed plate.

[0037] In another possible embodiment, the locking device includes an insertion rod fixed to the end of the extended rod 11 of the push rod mechanism 1, and a slot 41 is provided on the baffle 4. The insertion rod is locked in the slot 41 when the aerial passenger device does not exceed the set speed threshold; when the aerial passenger device reaches or exceeds the set speed threshold, the push rod mechanism 1 drives the insertion rod to be pulled out of the slot 41.

[0038] The push rod mechanism 1 in the above embodiment is configured as an oil cylinder or a gas cylinder.

[0039] refer to Figure 1 and Figure 3 In some possible embodiments, a limit groove 42 is provided on both sides of the baffle 4, and a wire rope avoidance groove 43 is provided at the bottom of the baffle 4. When the baffle 4 moves down to block the rope gripper, the wire rope 8 is arranged in the wire rope avoidance groove 43; two limit rods 6 are provided on the fixing seat 3, and the two limit rods 6 are respectively arranged in the two limit grooves 42. The two limit rods 6 and the limit grooves 42 cooperate to guide the baffle 4 so that the baffle 4 falls smoothly. Upper blocks 44 are provided on both sides of the top of the baffle 4, and the two upper blocks 44 are used to block the two limit rods 6.

[0040] refer to Figure 1 In some possible embodiments, the two limiting rods 6 are fixed with limiting plates 5, and the baffle plate 4 is arranged in the space between the fixing seat 3 and the limiting plates 5. The limiting plates 5 need to have a certain strength, and the limiting plates 5 are the main bearing plates when the baffle plate 4 falls to block the locking device.

[0041] refer to Figure 1 and Figure 5 When this embodiment is used specifically, when it is detected that the wire rope 8 is overspeeding, the speed signal of the wire rope 8 is transmitted to the control box. After receiving the signal, the control box sends an instruction to the control valve connected to the push rod mechanism 1, and controls the push rod mechanism 1 to move through the control valve. After receiving the instruction, the push rod mechanism 1 extends its rod 11 to act on the rod portion 73 of the blocking member 7, pushing the rod portion 73 to rotate around the hinge point of the blocking member 7, so that the hook portion 72 of the blocking member 7 moves out of the slot 41. At this time, the baffle 4 is freely dropped to the set height through the guidance of the two limit rods 6, thereby blocking the rope gripper.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or modify part or all of the technical solutions, or replace part or all of the technical features by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
