Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a hoisting device used for installing a single-channel steel structure corridor. Background Art

[0002] For metallurgical engineering renovation, expansion and technical upgrading and renovation projects, a steel structure corridor needs to be added above the single channel between the grid greenhouses. The channel width is generally 5-7m, with drainage ditches on both sides. The channel is narrow and large truck cranes and crawler cranes cannot enter the site. According to conventional construction methods, the corridor cannot be assembled as a whole on site, nor can it be hoisted as a whole. It can only be assembled in pieces, which makes construction difficult and the construction progress slow. Due to the narrow construction site and the existence of obstacles such as original buildings on both sides, there is only a single channel on site, which will result in vehicles being unable to pass after the bracket is installed. The conventional method of using two or more truck cranes to install the corridor cannot be used to install the corridor in a single channel environment.

[0003] In the prior art, the patent with publication number CN 109723218 A discloses a method for hoisting a corridor in a restricted area that needs to pass through an upper obstacle. A roller is installed at one end of the corridor, and a winch is used to cooperate with two cranes to continuously adjust the inclination angle of the corridor to finally pass through the upper obstacle and hoist it above the obstacle. This method can install the corridor by adjusting the inclination angle of the corridor, but since this method requires two cranes to cooperate with each other, and in a single channel, it is impossible to achieve the simultaneous movement of two cranes, therefore, this method is not suitable for the installation of a corridor with a single channel structure.

[0004] In view of this, it is necessary to design a hoisting device for the installation of a single-channel steel structure corridor to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a hoisting device for installing a single-channel steel structure corridor, which can realize the inclined hoisting of the corridor by using a crane under a single channel, thereby realizing the continuous installation of the steel structure corridor in the single channel.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A hoisting device for installing a single-channel steel structure corridor, comprising:

[0008] Lifting point, connected to the lifting rope;

[0009] The two ends of the beam are connected to the lifting points through connectors to form a triangular load-bearing structure;

[0010] A first suspension rope is fixed to one end of the crossbeam, and a free lower end of the first suspension rope is used to connect to a first suspension point of a suspended object; and

[0011] The second suspension rope is arranged at the other end of the beam through a rope winding structure, and the free lower end of the second suspension rope is used to connect the second suspension point of the suspended object; the inclination angle of the suspended object can be adjusted by adjusting the length of the second suspension rope through the rope winding structure.

[0012] As a further improvement of the present invention, a pulley is provided at one end of the crossbeam away from the first suspension rope.

[0013] As a further improvement of the present invention, one end of the second suspension rope passes around a pulley and is connected to the rope winding structure.

[0014] As a further improvement of the utility model, in the inclined state, along the direction from the first suspension rope to the second suspension rope, the inclination angle formed by the suspended object and the horizontal plane is less than or equal to 45°.

[0015] As a further improvement of the present invention, the rope winding structure is arranged in the middle of the beam.

[0016] As a further improvement of the present invention, the triangular bearing structure formed by the two connecting members and the crossbeam is an equilateral triangle.

[0017] As a further improvement of the present invention, the first suspension rope and the second suspension rope are symmetrically connected to two ends of the suspended object respectively.

[0018] As a further improvement of the present invention, the first hanging point is located at 1 / 4-1 / 3 of the length of the object being hung.

[0019] As a further improvement of the present utility model, the rope winding structure is a winch.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model connects two connecting parts at one end of the suspension rope away from the crane, and connects the two connecting parts to the beam at one end away from the suspension rope, so that a stable triangular bearing structure is formed between the two connecting parts and the beam. The beam can be used as a bearing part, and the rope winding structure can be installed on the beam. At the same time, a first suspension rope with one end fixed on the beam and a second suspension rope connected to the rope winding structure are respectively arranged at both ends of the beam. Then, the rope winding structure can be used to adjust the suspension length of the second suspension rope, so that when the two suspension ropes are connected to the suspended object, that is, the corridor, the inclination angle of the corridor can be adjusted by adjusting the suspension length of the second suspension rope, thereby achieving the installation of the corridor in a single channel by adjusting the lifting angle of the corridor by using a crane.

[0022] 2. The utility model utilizes a design in which one end of a lifting rope is connected to two connecting pieces and a crossbeam is connected between the two connecting pieces. This design can not only adjust the single-point suspension of the lifting rope to a double-point suspension, and then cooperate with a winch to adjust the angle of the corridor using a crane, but also utilize the triangular structure formed by the two connecting pieces and the crossbeam to enhance the stability of the corridor during hoisting, thereby realizing the installation of a single-channel corridor.

[0035] See also Figure 1-Figure 2 As shown, the utility model provides a hoisting device for installing a single-channel steel structure corridor, comprising:

[0036] A lifting point connected to the lifting rope 11;

[0037] The two ends of the crossbeam 30 are connected to the lifting points through the connecting pieces 20 to form a triangular bearing structure;

[0038] A first suspension rope 51 is fixed to one end of the cross beam 30, and a free lower end of the first suspension rope 51 is used to connect to a first suspension point of a suspended object; and

[0039] The second suspension rope 52 is arranged at the other end of the beam 30 through a rope winding structure, and the free lower end of the second suspension rope 52 is used to connect the second suspension point of the suspended object; the inclination angle of the suspended object can be adjusted by adjusting the length of the second suspension rope 52 through the rope winding structure.

[0040] Specifically, the two connecting members 20 are respectively the first steel wire rope and the second steel wire rope. In this embodiment, two lifting ears 31 are arranged on the upper surface of the crossbeam 30 at intervals. Figure 2 ), the two steel wire ropes are respectively connected to the two lifting ears 31, so that the triangular bearing structure formed between the two steel wire ropes and the crossbeam 30 is an equilateral triangle, and the triangular bearing structure can improve the stability of the lifting to a certain extent during the lifting process of the suspended object, i.e., the corridor 70 of this embodiment, and at the same time, it can also make the crossbeam 30 a load-bearing member with a certain load-bearing capacity, so that the rope winding structure can be set on the crossbeam 30, and then the suspension length of the second suspension rope 52 can be adjusted by the rope winding structure.

[0041] Specifically, the rope winding structure is a winch 40 , and the winch 40 is disposed in the middle of the beam 30 .

[0042] Specifically, Figure 2As shown, a lifting ring 32 is also provided on the lower surface of the beam 30, and the first suspension rope 51 is fixed to one end of the beam 30 through the lifting ring 32; a through hole 33 is provided at the end of the beam 30 away from the first suspension rope 51, and a pulley 34 is also provided at the end of the beam 30 away from the first suspension rope 51, and one end of the second suspension rope 52 passes through the through hole 33 and around the pulley 34 and then is connected to the winch 40, so that under the action of the winch 40, the suspension length of the second suspension rope 52 can change. In this process, the suspension length of the first suspension rope 51 is always fixed, and then by adjusting the suspension length of the second suspension rope 52, the corridor 70 can be switched between a horizontal state and an inclined state with a certain inclination angle with the horizontal plane. Exemplarily, in the inclined state, along the direction from the first suspension rope 51 to the second suspension rope 52, the inclination angle formed by the corridor 70 and the horizontal plane is Figure 4 α in is less than or equal to 45°.

[0043] Specifically, the first suspension rope 51 and the second suspension rope 52 are symmetrically connected to the two ends of the corridor 70, and exemplarily, the first suspension point is located at 1 / 4-1 / 3 of the length of the corridor 70, and the corresponding second suspension point 51 is located at 2 / 3-3 / 4 of the length of the corridor 70. The connection position of the first suspension rope 51 and the second suspension rope 52 with the corridor 70 is set to facilitate the adjustment of the inclination of the corridor 70 by controlling the suspension length of the second suspension rope 52, so as to avoid the connection points between the first suspension rope 51 and the second suspension rope 52 and the corridor 70 being too close to affect the adjustment of the inclination of the corridor 70 and its hoisting, and to avoid the connection points between the first suspension rope 51 and the second suspension rope 52 and the corridor 70 being too far to reduce the adjustment efficiency of the inclination.

[0044] For example, Figure 7 As shown, when the hoisting device is used to install the corridor 70, no column support is installed at the lower part of the bracket 80 used to install the corridor 70, so that the transport vehicle 60 can pass through the bracket 80 along a single channel and transport the corridor 70 to the bottom of the bracket 80 to be installed.

[0045] Specifically, when installing the corridor 70, the corridor 70 is placed on the transport vehicle 60, and the transport vehicle 60 is passed between the two brackets 80 for installing the corridor 70 ( Figure 3 ); the crane 10 drives the hoisting device connected to the hoisting rope 11 thereon to move to the vicinity of the outer side of the bracket 80, fix the first suspension rope 51 and the second suspension rope 52 on the corridor 70 at one end away from the crossbeam 30, and drive the transport vehicle 60 away, and use the winch 40 to reduce the suspension length of the second suspension rope 52, so that the corridor 70 changes from a horizontal state to an inclined state with a certain inclination angle with the horizontal plane, so that in the inclined state, along the vertical downward direction, the length of the left and right ends of the corridor 70 is less than the distance between the two brackets 80 ( Figure 4 ), and then when the crane 10 controls the lifting rope 11 to rise, the corridor 70 can rise to pass over the bracket 80 and be located above the bracket 80 ( Figure 5 ); Use the crane 10 to control the suspension rope 11, so that the low point of the inclined corridor 70 falls on the crossbar 81 of the corresponding side bracket 80, and then use the hoist 40 to increase the suspension length of the second suspension rope 52, so that the other end of the corridor 70 falls on the crossbar 81 of the other side bracket 80, and the installation of the current corridor 70 is completed ( Figure 6 ); Place adjacent brackets 80 in a certain direction, and then use the transport vehicle 60 and the lifting device to install the adjacent corridors 70, and then gradually complete the installation of the rigid structure corridor 70 in the single channel.

[0046] 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 preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
