Detailed ways

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

The utility model provides a hoist for an electric pole. The hoist as shown in Figure 1 includes: a hoisting part, which is detachably installed on the pole, and the hoisting part includes a sling 10 and a hoisting pulley 20; the sling 10 is wound around the hoisting pulley 20; the driving part 30 , is detachably installed on the pole, the driving part 30 is drivingly connected with the hoisting part, and drives the hanging rope 10 to retract.

The hoist in the utility model realizes hoisting and hoisting by installing the hoisting pulley 20 on the pole and winding the hoisting rope 10 on the hoisting pulley 20, and then driving the hoisting rope 10 with the driving part 30 to retract. Preferably, the hoisting pulley 20 is installed on the top of the pole, so that the hoisting object has a larger range of motion. Preferably, the lifting rope 10 is a steel wire rope. Since the steel wire rope itself has high strength, the lifting rope 10 can lift heavier lifting objects and has better load-bearing capacity. Simultaneously, the hoist in the utility model has the characteristics of simple structure.

In the embodiment shown in Figures 1 and 2, the hoisting part further includes a connecting rod 40 and a connecting rod mounting seat 50, the hoisting pulley 20 is arranged on the connecting rod 40, and the connecting rod 40 is detachably connected to the connecting rod mounting seat 50 , the connecting rod mount 50 is detachably mounted on the upper end of the pole. Preferably, the hoisting pulley 20 is detachably mounted on the connecting rod 40 . Since the hoisting pulley 20, the connecting rod 40, and the connecting rod mounting seat 50 can all be disassembled, it is only necessary to install the parts when using the hoisting part, which reduces the complexity of the manufacturing process; at the same time, when a part is damaged, only This part is replaced, thereby reducing the cost of use. Preferably, the connecting rod installation seat 50 is a clamping hoop, which is a kind of hardware commonly used on electric poles and has good stability.

Preferably, the hoisting pulley 20 in the utility model includes a hoisting pulley 21 and a reversing pulley 22, the hoisting pulley 21 is arranged on the first end of the connecting rod 40 close to the object to be hoisted, and the reversing pulley 22 is arranged near the connecting rod 40 The second end of the driving part 30 (please refer to FIG. 1 and FIG. 2 ). Since the hoisting pulley 20 is set as two pulleys with a certain distance between the two pulleys, the distance of the lifting rope 10 between the two pulleys is increased, thereby ensuring that the hoisting rope 10 is wound during the lifting of heavy objects. The suspension rope 10 on both sides of the hoisting pulley 20 will not be entangled, which will bring trouble to the hoisting work. Certainly, the number of the hoisting pulley 20 can also be only one, and a hoist with only one hoisting pulley 20 can also realize the hoisting of the hoisted object.

The hoist in the utility model also includes a fixed support 60 and a support mounting seat 70, and the support mounting seat 70 is detachably connected with the fixed support 60; the fixed support 60 is detachably installed on the lower end of the pole through the support mounting seat 70; The part 30 is fixedly arranged on the fixing bracket 60 . Preferably, the bracket mounting seat 70 is a clamping hoop, since the fixing bracket 60 is detachably connected with the clamping hoop, it is convenient to install and disassemble the fixing bracket 60 on the pole. Preferably, the fixing bracket 60 is a triangular bracket. The triangular bracket is more stable in force and has a larger load-bearing capacity.

In an embodiment not shown, the drive part 30 includes a drive shaft 31 and a power crank 32, the power crank 32 is connected to the drive shaft 31; the drive shaft 31 is pivotally mounted on the fixed bracket 60, and the suspension rope 10 One end is wound on the drive shaft 31. Preferably, the power crank 32 is driven by manpower, thereby simplifying the structure of the driving part 30 in the hoist. The driving shaft 31 also continuously winds the suspension rope 10 fixed on the driving shaft 31 around the shaft when the power crank 32 rotates. In an embodiment not shown, a motor may also be used to drive the drive shaft 31 to rotate. Since the driving shaft 31 is installed on the fixed bracket 60, and the fixed bracket 60 is installed on the electric pole, the driving part 30 is stably connected with the electric pole, which is more conducive to the smooth hoisting of the lifting object.

In the embodiment shown in Fig. 1 and Fig. 3, the driving part 30 includes a drive shaft 31, a driven shaft 33 and a power crank 32, and the power crank 32 is connected with the drive shaft 31; the drive shaft 31 and the driven shaft 33 are respectively Pivotably installed on the fixed bracket 60, one end of the suspension rope 10 is wound on the driven shaft 33; the driving shaft 31 is provided with a driving gear, and the driven shaft 33 is provided with a driven gear matched with the driving gear. Preferably, the radius of the driving shaft 31 is smaller than that of the driven shaft 33 , furthermore, the driving gear on the driving shaft 31 is smaller than the driven gear on the driven shaft 33 . Since the driving gear is smaller than the driven gear and the two gears cooperate with each other, not only the motion transmission between the driving shaft 31 and the driven shaft 33 is realized, but also the rotation speed of the driven shaft 33 is reduced. Because one end of the sling 10 is wound on the driven shaft 33, the sling 10 is more wound on the shaft while the driven shaft 33 rotates, and because the moving speed of the driven shaft 33 is low, the speed of hoisting the hoisting objects is reduced. The process is smoother.

Preferably, a drive shaft support 61 for supporting the drive shaft 31 and a driven shaft support 62 for supporting the driven shaft 33 are provided on the fixing bracket 60 in the present invention. Preferably, the drive shaft 31 is pivotally connected to the drive shaft support 61 through a bearing, and the driven shaft 33 is pivotally connected to the driven shaft support 62 through a bearing. In the embodiment shown in Figure 3 and Figure 4, the drive shaft support 61 and the driven shaft support 62 are all fixed on the fixed bracket 60 by bolt connection, and the drive shaft support 61 and the driven shaft support 62 Bearings are respectively arranged inside, and are connected with the drive shaft 31 and the driven shaft 33 through the bearings. Since the bearing is a wearable part, the normal operation of the hoist can be guaranteed by replacing the bearing. In another non-illustrated embodiment, the drive shaft support 61 and the driven shaft support 62 can be installed on the fixing bracket 60 by welding.

Preferably, in the embodiment shown in FIG. 4 , the hoist further includes a reverse stop piece 80 for limiting the hoisting position of the sling 10, and one end of the reverse stop piece 80 is pivotally arranged on the fixed bracket. 60, the other end of the reverse stop piece 80 is matched with the driven gear.

Further, the pivoting portion of the reverse stop piece 80 is a positioning sleeve for the pin shaft to pass through. Preferably, the other end of the reverse stop piece 80 is disposed on the upper part of the driven gear and snapped into the gear groove of the driven gear. In another non-illustrated embodiment, if the reverse stop piece 80 is arranged at other positions of the fixed bracket 60, or the winding direction of the suspension rope 10 on the driven shaft 33 changes, it is necessary to adjust the reverse stop piece 80. The setting method of 80 is changed accordingly. In order to ensure that the reverse stop piece 80 can realize the reverse stop function, the setting of the reverse stop piece 80 should be determined according to the specific setting method of the suspension rope 10 and the rotation method of the driven gear, etc., and its specific setting method It should be based on the principle of preventing the free extension of the suspension rope 10 without limiting the contraction of the suspension rope 10 . Please refer to FIG. 4 , since the reverse stop piece 80 is an L-shaped stop piece and is arranged on the upper part of the driven gear, so the effects of the driven shaft 33 not stopping forward rotation and reverse rotation stopping can be realized.
