The main rope is fixed in position, and the traction rope can move forward and backward relative to the main rope through the operation of the cable car. The conventional transportation method is: construction materials and small tools are placed in containers, and the containers are hung on the traction rope for transportation. This transportation method can only transport small quantities in batches because the transportation weight is entirely borne by the traction rope, which has low transportation efficiency and reduces the safety of freight ropeway operation.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] This embodiment provides a cargo cableway lifting device, such as Figure 1 and Figure 2 As shown, the cargo ropeway hoisting device comprises a main bearing frame 1, which is a plate body bent into an η shape and made of steel plate. One end of the main bearing frame 1 is a bent section, on which a pulley 2 matching the main rope of the cargo ropeway is installed; the pulley 2 is rotatably installed on the bent section of the main bearing frame 1 through an axle, and a line groove 5 matching the main rope of the cargo ropeway is provided on the pulley 2. A clamping assembly 3 capable of clamping the traction rope of the cargo ropeway is provided in the middle of the main bearing frame 1, and a hook assembly 4 matching the hoisting is provided at the other end of the main bearing frame 1, and the hook assembly 4 can be a commercially available hook.

[0021] like Figure 1 and Figure 2 As shown, the clamping assembly 3 includes a fixed clamping plate 6, a movable clamping plate 7 and a bolt 8; the fixed clamping plate 6 is L-shaped, and one side of the fixed clamping plate 6 is welded and fixed to the main load-bearing frame 1; the fixed clamping plate 6 and the main load-bearing frame 1 are both provided with through holes for the matching bolts 8 to pass through, and the bolts 8 pass through the main load-bearing frame 1 and the fixed clamping plate 6 through the through holes and then are threadedly connected with the movable clamping plate 7. Under the limiting effect of the fixed clamping plate 6, the movable clamping plate 7 can move to one side of the fixed clamping plate 6 through the bolt 8, thereby clamping the traction rope of the freight ropeway; the fixed clamping plate 6 and the movable clamping plate 7 are both provided with arc-shaped clamping grooves 9, and after the traction rope of the freight ropeway is clamped, it is located in the arc-shaped clamping grooves 9.

[0022] Combined with the structure of the above freight ropeway lifting device, according to Figure 3First, the bolt 8 is rotated in the opposite direction to reserve a gap between the fixed clamp plate 6 and the movable clamp plate 7 for the traction rope 11 of the freight ropeway to enter; then the main bearing frame 1 is mounted on the main rope 10 of the freight ropeway to ensure that the main rope 10 of the freight ropeway is located in the wire groove 5 of the pulley 2; then the bolt 8 is turned over to allow the fixed clamp plate 6 and the movable clamp plate 7 to clamp the traction rope 11 of the freight ropeway; finally, after confirming that the freight ropeway hoisting device is firmly installed, the carrier containing construction materials and small tools is mounted on the hook assembly 4.

[0023] The cable drive device is started, and the cable drive device drives the traction rope 11 of the freight ropeway to move, and the main rope 10 of the freight ropeway is fixed in position. At this time, the freight ropeway object hoisting device and the carrier move on the main rope 10 with the movement of the traction rope 11 of the freight ropeway. The freight ropeway object hoisting device can transfer the transportation weight to the main rope 10 and the traction rope 11 of the freight ropeway through the pulley 2 and the clamping assembly 3 on the main bearing frame 1, thereby increasing the transportation load. Example 2

[0024] On the basis of embodiment 1, considering the convenience of unloading, this embodiment further proposes a hook assembly 4, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the hook assembly 4 includes a hook mounting frame 12 and a hook 13 .

[0025] The upper part of the hook mounting frame 12 is a connecting plate 14 welded and fixed to the main bearing frame 1, and the lower part is composed of a first mounting plate 15 and a second mounting plate 16, and a gap for mounting the hook 13 is left between the first mounting plate 15 and the second mounting plate 16. The cross section of the hook 13 is C-shaped, and the hook 13 is rotatably mounted between the first mounting plate 15 and the second mounting plate 16 through a pin shaft; at the same time, a locking rod 17 capable of controlling the rotation of the hook 13 is also installed between the first mounting plate 15 and the second mounting plate 16, and the locking rod 17 is rotatably mounted between the first mounting plate 15 and the second mounting plate 16 through a pin shaft 19, and is located above the hook 13.

[0026] When the lock rod 17 rotates clockwise to a vertical state, the lock tongue 18 on one side of the lock rod 17 is buckled into the C-shaped opening of the hook 13, and drives the hook 13 to rotate counterclockwise, so that the hook body on the lower side of the hook 13 rotates upward. After the lock rod 17 rotates to a vertical state, the lock rod 17 is fixed to the connecting plate 14 on the upper part of the hook 13 mounting frame 12 by a rope; at this time, the hook body on the upper part of the hook 13 is limited between the first mounting plate 15 and the second mounting plate 16 by the pin 19 of the lock rod 17 and the lock tongue 18.

[0027] The hook assembly 4 adopting this structure can realize the convenience of unloading. When unloading, the rope between the locking rod 17 and the hook mounting frame 12 is removed. At this time, the hook 13 is disengaged from the limit of the locking tongue 18, and rotates clockwise to the C row opening downward due to the load, and the carrier is disengaged from the hook 13.

[0028] Furthermore, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, considering the safety during transportation, in this embodiment, a spring clip 20 for cooperating with the hook 13 is also installed between the first mounting plate 15 and the second mounting plate 16; the spring clip 20 is a structural device existing on the existing hook, and its structure and working principle will not be described in detail here. The spring clip 20 can prevent the carrier from detaching from the hook 13 during transportation.

[0029] The utility model may also have various changes and improvements, which all fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
