Fig. 1 shows a schematic structural diagram of a lifting appliance according to an embodiment of the present utility model. The lifting appliance provided by the embodiment of the utility model is suitable for pedal blocks with preformed holes on two sides. Specifically, the preformed holes are formed in the prefabricating process of the pedal block in a sleeve embedding mode, wherein the preformed holes on two sides of the pedal block can be arranged oppositely or in a staggered mode.
Referring to fig. 1, a lifting appliance provided by an embodiment of the present utility model includes: a plurality of bolts 2, a plurality of lifting ropes 3 and a supporting frame 4. The bolts 2 correspond to the preformed holes 1.1 on the pedal block 1, and the bolts 2 are connected to the hoisting device 5 through the hoisting ropes 3. The supporting frame 4 is connected to the lifting device 5 and is located between the plurality of lifting ropes 3, and the supporting frame 4 is used for supporting the plurality of lifting ropes 3 so that the plurality of bolts 2 are distributed on two sides of the pedal block 1. In particular use, the pins 2 are used to be inserted into the corresponding preformed holes 1.1 so that the lifting device 5 can lift the pedal block 1.

In addition, in the scheme, the lifting rope 3 is supported by the supporting frame 4 so that the bolts 2 are distributed on two sides of the pedal block 1, so that the lifting rope 3 can keep a distance from the pedal block 1 in a lifting state, friction between the lifting rope 3 and the pedal block 1 is avoided, the quality risk that the pedal block 1 is worn by the lifting rope 3 is reduced, and the service life of the lifting rope 3 is prolonged. In addition, the supporting frame 4 can also separate the lifting ropes 3, so that the lifting ropes 3 are prevented from winding before and after lifting, and the lifting efficiency is further affected.
In the embodiment of the utility model, the number of the bolts 2 is 4, and the 4 bolts 2 are equally distributed on two sides of the pedal block 1 under the action of the supporting frame 4. It should be understood that the two sides of the foot pedal block 1 are respectively provided with a preformed hole 1.1 corresponding to the position of the bolt 2.
In an alternative embodiment, the cross-sectional shape of the latch 2 includes, but is not limited to, circular, square, rectangular, and the like. Illustratively, the cross-sectional shape of the plug 2 is circular, which may reduce the difficulty of machining the plug 2.
When the bolt 2 is specifically arranged, the bolt can be formed by cutting and processing round steel with the diameter of 100 mm.
In addition, in order to ensure that the plug 2 can be inserted into the preformed hole 1.1 smoothly, the cross-sectional dimension of the plug 2 should be at least slightly smaller than the cross-sectional dimension of the preformed hole 1.1. For example, in a specific setting, the radius of the spigot 2 is 100mm and the radius of the preformed hole 1.1 is 105mm.
In the embodiment of the utility model, the hoisting device 5 is a crane. For example: the crane may be one of a crawler crane, a truck crane, a tyre crane, a tower crane and a mast crane.
In the embodiment of the utility model, the bolt 2 comprises an inserting section 2.1 and an exposing section 2.2, the inserting section 2.1 is connected with the exposing section 2.2, the inserting section 2.1 is used for being inserted into the reserved hole 1.1, and the exposing section 2.2 is used for being connected with the lifting rope 3. When the lifting device is specifically used, the exposed section 2.2 can be used as a stress end of the bolt 2 besides being connected with the lifting rope 3, and before lifting begins or after lifting in place, an operator can apply a pulling force to the exposed section 2.2 to enable the bolt 2 to move in a direction away from the side face of the pedal block 1, so that the bolt 2 reaches an insertion position or withdraws from the reserved hole 1.1.
When the device is specifically arranged, the insertion section 2.1 and the exposed section 2.2 can be connected and fixed through a threaded connector or a welding mode, and can also be integrally processed and molded. In the embodiment of the utility model, the insert section 2.1 and the exposed section 2.2 are preferably integrally formed, so that the connection strength of the insert section 2.1 and the exposed section 2.2 can be improved.
In an alternative embodiment, the exposed section 2.2 is connected with a traction rope 6. The embodiment of the utility model shows that the end of the exposed section 2.2 remote from the insertion section 2.1 is provided with a connecting lug 2.3, the exposed section 2.2 being connected to the traction rope 6 via the connecting lug 2.3. When the pedal block is specifically used, an operator can apply tension to the exposed section 2.2 through the traction rope 6 so that the bolt 2 can move in the direction away from the side face of the pedal block 1, and therefore the exposed section 2.2 can be prevented from being separated from the control of the operator due to the change of the height in the moving process. Specifically, in the process of moving the latch 2 in a direction away from the side of the pedal block 1, the height of the latch 2 is changed, and when the height of the latch 2 reaches a height that cannot be reached by a human hand, the latch 2 falls from the human hand, so that the control of an operator is released.
When the plug is specifically arranged, the connecting lug 2.3 can be an independent structure arranged on the exposed section 2.2, and can also be formed by punching holes on the plug 2 in the processing process of the plug 2. In the embodiment of the utility model, the connecting lug 2.3 is preferably formed by forming an opening in the processing process of the bolt 2, so that the connection strength can be improved, and the stability in the hoisting process is ensured.
In an alternative embodiment, the length of the exposed section 2.2 is less than or equal to the length of the inserted section 2.1, and the end of the exposed section 2.2 adjacent to the inserted section 2.1 is connected to the lifting rope 3. Illustratively, the exposed section 2.2 has a length of 400mm and the insert section 2.1 has a length of 500mm. When the lifting device is specifically used, the first end of the lifting rope 3 is connected with the lifting device 5, the second end of the lifting rope 3 is sleeved on the exposed section 2.2, and an operator can adjust the angle of the bolt 2 by applying downward pressure to the exposed section 2.2, so that the bolt 2 can meet the insertion requirements of different angles. It will be appreciated that the closer the exposed section 2.2 is to the lifting rope 3, the less force is required to adjust the angle of the bolt 2, and conversely, the more the exposed section 2.2 is to the lifting rope 3, the more force is required to adjust the angle of the bolt 2. Therefore, with the above-described scheme, the force required to adjust the angle of the plug pin 2 can be reduced, so that the operation difficulty can be reduced.
In an alternative embodiment, the end of the exposed section 2.2 near the insertion section 2.1 is provided with a baffle 2.4, and in particular use, the baffle 2.4 can prevent the lifting rope 3 from moving towards the insertion section 2.1, so as to avoid reducing the insertion depth of the insertion section 2.1 due to the movement of the lifting rope 3, thereby causing a safety hazard. In addition, the baffle plate 2.4 can also be used as an indicating structure for indicating the insertion depth of the bolt 2.
In the embodiment of the present utility model, the supporting frame 4 is a rectangular frame, and the supporting frame 4 supports the plurality of suspension ropes 3 through opposite sides in the width direction thereof so that the plurality of pins 2 are distributed at both sides of the pedal block 1.
In an alternative embodiment, the width of the support frame 4 is slightly greater than the distance between the sides of the foothold 1 with the preformed holes 1.1. When the lifting rope 3 is particularly used, the supporting frame 4 can support the lifting rope 3, so that the distance between the opposite lifting ropes 3 in the width direction is slightly larger than the distance between two sides of the pedal block 1 with the reserved holes 1.1, that is, the lifting rope 3 can keep a distance with the pedal block 1 in the state that the bolt 2 is inserted into the reserved holes 1.1, friction between the lifting rope 3 and the pedal block 1 is avoided, the quality risk that the pedal block 1 is worn by the lifting rope 3 is reduced, and the service life of the lifting rope 3 is prolonged.
In an alternative embodiment, the support frame 4 is further provided with lifting lugs 4.1, and the support frame 4 can be connected to the lifting device 5 via the lifting lugs 4.1. For example, in specific use, the lifting lugs 4.1 are connected to slings of the lifting device 5, so as to realize the connection of the support frame 4 to the lifting device 5.
The embodiment of the utility model also provides a hoisting system which comprises hoisting equipment 5 and a hoisting tool.
