Description

Technical Field

[0001] The present invention relates to a lifting device, in particular to a lifting device for overhauling Euro silos equipment. Background Art

[0002] Euro coal storage is a fully enclosed coal storage method, which has the advantages of environmental protection, high automation, good coal storage characteristics, low investment and small floor area. The common height of the Euro silo body can reach 50 meters, and the storage volume can be 100,000 cubic meters. In power generation enterprises, in order to meet the necessary coal storage volume and place multiple types, usually 2 or more Euro silos are actually used for coal storage. These Euro silos are arranged at relatively small intervals and along the coal conveying line.

[0003] However, the wall thickness of the Euro silo is only 0.5 - 1 m. The coal stacking and reclaiming equipment of the Euro silo is arranged inside the silo, and the height of the stacking and reclaiming equipment can change according to the change of the coal stacking height. The top of the Euro silo is provided with coal conveying equipment and a coal conveying trestle for feeding. For the equipment inside the Euro silo, including various electrical and mechanical devices, maintenance and overhaul are inevitably required. Then these equipment need to enter and exit the Euro silo. Considering the strength requirement of the Euro silo wall, no inspection hole is set on the wall, so the equipment cannot directly pass through the Euro silo wall and can only enter and exit through the lifting hole on the top of the silo. Since the position of the top of the Euro silo is relatively high, to complete the entry and exit overhaul work of such equipment, currently mainly a 300 - 500 ton truck crane is used to complete it. However, the method using a truck crane has high cost and slow response speed, increasing the cost and time of the overhaul work. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above - mentioned defects existing in the prior art and provide a lifting device for overhauling Euro silos equipment, which has real - time response, simple structure, does not occupy ground space and has low cost.

[0005] This embodiment provides a lifting device for overhauling Euro silos equipment, which solves the lifting requirement for overhauling the equipment of two adjacent Euro silos 3, greatly facilitates the lifting requirement during the overhaul and maintenance of the equipment of Euro silo 3, and the single - rail lifting device is easy to repair and has extremely low use cost, can have real - time response, does not occupy ground space and will not interfere with other equipment on the site.

[0006] The purpose of the present invention can be realized by the following technical solutions:

[0007] A lifting device for the maintenance of Euro bins, which is used for the hoisting of maintenance equipment in two adjacent Euro bins. The top surfaces of the two Euro bins are both provided with hoisting holes. The device includes a metal gantry, a track and an electric hoist. The metal gantry is arranged on the circumferential end faces at the tops of the walls of the two Euro bins. The metal gantry includes a support frame and a mounting table on the support frame. The track is suspended on the mounting table and passes directly above the hoisting holes on the two Euro bins. The electric hoist is slidably arranged on the track through a trolley. The electric hoist can slide along the track through the trolley, and can hoist the maintenance equipment in the two adjacent Euro bins in and out, meeting the hoisting requirements of the two Euro bins at the same time. The structure is simple and the efficiency is high.

[0008] Furthermore, since the civil engineering foundations of the two Euro bins are independent of each other, the settlement amounts of the two Euro bins may be different. The ends of the legs on one of the Euro bins are fixed to the circumferential end faces at the tops of the walls of the Euro bin through hinge supports. The axes of rotation of all the hinge supports are coaxial, ensuring that the metal gantry can rotate around the axis of the hinge support. The ends of the legs on the other Euro bin are fixed to the circumferential end faces at the tops of the walls of the Euro bin through sliding supports. The sliding directions of all the sliding supports are the same, ensuring that there is a sliding amount between the metal gantry and the Euro bin. The metal gantry has degrees of freedom in the horizontal and axial directions, reducing the influence of different settlement amounts of the two Euro bins on the lifting device, with good safety and long service life.

[0009] Furthermore, the hinge support includes a first end plate and a second end plate. The first end plate is fixed to the end of the leg, and the second end plate is embedded in the circumferential end face. A first hinge plate is provided on the first end plate, and a second hinge plate is provided on the second end plate. The first hinge plate and the second hinge plate are hinged through a first pin shaft. The sliding support includes a third end plate and a fourth end plate. The third end plate is fixed to the end of the leg, and the fourth end plate is embedded in the circumferential end face. A third hinge plate is provided on the third end plate, and a fourth hinge plate is provided on the fourth end plate. The third hinge plate and the fourth hinge plate are hinged through a second pin shaft.

[0010] Furthermore, the second pin shaft includes a roller and sliding shafts coaxially fixed at both ends of the roller. Waist-shaped holes are opened on both the third hinge plate and the fourth hinge plate. The sliding shafts pass through the waist-shaped holes on the third hinge plate and the fourth hinge plate, and the sliding shafts can slide along the direction of the waist-shaped holes. The side wall of the roller contacts the third hinge plate and the fourth hinge plate. The roller plays a supporting role, reducing the force on the sliding shafts, with stable structure and good safety.

[0011] Further, a first connecting rod is provided on the installation table, a connecting plate is fixed on the track, and the end of the first connecting rod is connected to the connecting plate through a second connecting rod, so that the track is stably suspended below the installation table, and the trolley can pass through the metal gantry.

[0012] Further, the installation table is a trapezoidal frame formed by connecting the heads and tails of connecting rods to adapt to the circumferential end face shape of the top of the Eurobin silo wall. The cross-section of the connecting rod is I-shaped, with large structural stiffness and light weight, improving safety and layout cost. A number of reinforcing rods are connected between the upper base and the lower base of the trapezoidal frame. The cross-section of the reinforcing rod is I-shaped, improving the structural stiffness of the installation table and having good safety.

[0013] Further, a second horizontal tie rod and two crossed diagonal tie rods are connected between two legs at symmetric positions of the two Eurobin silos, and a first horizontal tie rod is connected between two adjacent legs of each Eurobin silo, improving the tensile strength of the metal gantry.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) In the present invention, a metal gantry is erected between two adjacent Eurobin silos. There is a lifting hole at the top of the Eurobin silo. A track passing directly above the lifting hole is suspended on the metal gantry. An electric hoist is slidably arranged on the track, which can lift the maintenance equipment in and out of two adjacent Eurobin silos. There is no need to use a truck crane additionally, which can respond in real time, with high efficiency. The lifting requirements of two Eurobin silos are satisfied by one track, with simple structure, low cost and easy maintenance. At the same time, the lifting device is arranged at the top of the Eurobin silo, not occupying the ground space and not interfering with other equipment on the site;

[0016] (2) In the present invention, the ends of the legs of one Eurobin silo are fixed on the circumferential end face of the top of the silo wall of this Eurobin silo through hinge supports, and the ends of the legs of the other Eurobin silo are fixed on the circumferential end face of the top of the silo wall of this Eurobin silo through sliding supports. The axes of rotation of all hinge supports are coaxial, and the sliding directions of all sliding supports are the same, so that the metal gantry has horizontal and axial degrees of freedom, reducing the influence of the different settlement amounts of the two Eurobin silos on the lifting device, with good safety and long service life;

[0017] (3) In the present invention, the second pin shaft includes a roller and sliding shafts coaxially fixed at both ends of the roller. Waist-shaped holes are opened on both the third hinge plate and the fourth hinge plate. The sliding shaft passes through the waist-shaped holes on the third hinge plate and the fourth hinge plate, and the sliding shaft can slide along the direction of the waist-shaped hole. The side wall of the roller contacts the third hinge plate and the fourth hinge plate. The roller plays a supporting role, reducing the force on the sliding shaft, with stable structure and good safety.

[0018] (3) The installation platform of the present invention is a trapezoidal frame formed by connecting the head and tail of connecting rods to adapt to the shape of the circumferential end face at the top of the wall of the Euro bin. The cross-section of the connecting rod is in the shape of an I-beam, which has high structural stiffness and light weight, improving safety and layout cost. A number of reinforcing rods are connected between the upper and lower bases of the trapezoidal frame. The cross-section of the reinforcing rod is in the shape of an I-beam, improving the structural stiffness of the installation platform and having good safety;

[0019] (4) A second horizontal tie rod and two intersecting diagonal tie rods are connected between two legs at symmetrical positions of the two Euro bins of the present invention. A first horizontal tie rod is connected between two adjacent legs on each Euro bin, improving the tensile strength of the metal gantry and having a long service life. Description of the Drawings

Detailed Description of the Invention

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation manners and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0030] As Figure 1 , in power generation enterprises, in order to meet the necessary coal storage capacity and place multiple types, usually 2 or more Euro silos 3 arranged along the coal conveyor trestle 1 are actually used for coal storage.

[0031] A hoisting device for overhauling Euro silo equipment, as Figure 1 , Figure 5 , Figure 5 and Figure 6 , is used for hoisting the overhaul equipment in two adjacent Euro silos 3. Hoisting holes 2 are provided on the top surfaces 31 of both Euro silos 3. The device includes a metal gantry 4, a track 5 and an electric hoist 6. The metal gantry 4 is arranged on the circumferential end faces 32 at the tops of the walls of the two Euro silos 3. The metal gantry 4 includes a support frame and a mounting platform 42 on the support frame. The track 5 is suspended on the mounting platform 42 and passes directly above the hoisting holes 2 on the two Euro silos 3. The electric hoist 6 is slidably arranged on the track 5 through a trolley 61. The electric hoist 6 can slide along the track 5 through the trolley 61, and can hoist the overhaul equipment in the two adjacent Euro silos 3 in and out. The hoisting requirements of the two Euro silos 3 can be satisfied simultaneously through one track 5. The structure is simple. When the hoisting device is in use, the electric hoist 6 moves to directly above the hoisting hole 2 through the trolley 61 and completes the hoisting in and out of the overhaul equipment, which can respond in real time and has high efficiency. The hoisting device is arranged on the top of the Euro silo 3, does not occupy the ground space, and will not interfere with other equipment on the site.

[0032] When one Euro silo 3 stores coal, it can store 90,000 tons of coal. When the Euro silo 3 adopts a civil engineering foundation, especially a soft soil layer foundation, settlement will occur. Since the civil engineering foundations adopted by the two Euro silos 3 are independent of each other, different settlement amounts may occur in each Euro silo 3 during the use period, and the height and spacing between the two Euro silos 3 will change. If the legs 41 of the metal gantry 4 are rigidly connected to the Euro silo 3, it is easily damaged. Therefore, the ends of the legs 41 on one of the Euro silos 3 are fixed on the circumferential end face 32 at the top of the wall of this Euro silo 3 through hinge supports 7, and the axes of rotation of all the hinge supports 7 are coaxial, ensuring that the metal gantry 4 can rotate around the axis of the hinge support 7. The ends of the legs 41 on the other Euro silo 3 are fixed on the circumferential end face 32 at the top of the wall of this Euro silo 3 through sliding supports 8, and the sliding directions of all the sliding supports 8 are the same, ensuring that there is a sliding amount between the metal gantry 4 and this Euro silo 3; the metal gantry 4 has degrees of freedom in the horizontal and axial directions, reducing the influence of different settlement amounts of the two Euro silos 3 on the hoisting device, with good safety and long service life.

[0033] The articulated support 7 includes a first end plate 71 and a second end plate 74. The first end plate 71 is fixed to the end of the leg 41, and the second end plate 74 is embedded in the circumferential end face 32. A first articulated plate 71 is provided on the first end plate 71, and a second articulated plate 73 is provided on the second end plate 74. The first articulated plate 71 and the second articulated plate 73 are articulated by a first pin shaft 75; the sliding support 8 includes a third end plate 81 and a fourth end plate 83. The third end plate 81 is fixed to the end of the leg 41, and the fourth end plate 83 is embedded in the circumferential end face 32. A third articulated plate 82 is provided on the third end plate 81, and a fourth articulated plate 85 is provided on the fourth end plate 83. The third articulated plate 82 and the fourth articulated plate 85 are articulated by a second pin shaft 84.

[0034] The second pin shaft 84 includes a roller 841 and sliding shafts 842 coaxially fixed at both ends of the roller 841. Waist-shaped holes 843 are formed on both the third articulated plate 82 and the fourth articulated plate 85. The sliding shafts 842 pass through the waist-shaped holes 843 on the third articulated plate 82 and the fourth articulated plate 85. The sliding shafts 842 can slide along the direction of the waist-shaped holes 843. The side wall of the roller 841 contacts the third articulated plate 82 and the fourth articulated plate 85. The roller 841 plays a supporting role, reducing the force on the sliding shafts 842, with stable structure and good safety.

[0035] A first connecting rod 9 is provided on the mounting table 42, and a connecting plate 11 is fixed on the track 5. The end of the first connecting rod 9 is connected to the connecting plate 11 through a second connecting rod 10, so that the track 5 is stably suspended below the mounting table 42, and the trolley 61 can pass through the metal gantry 4.

[0036] The mounting table 42 is a trapezoidal frame formed by connecting the ends of the connecting rods in sequence to adapt to the shape of the circumferential end face 32 at the top of the wall of the Euro bin 3. The cross-section of the connecting rod is in the shape of an I-beam, with large structural stiffness and light weight, improving safety and layout cost. A number of reinforcing rods 44 are connected between the upper base and the lower base of the trapezoidal frame. The cross-section of the reinforcing rod 44 is in the shape of an I-beam, improving the structural stiffness of the mounting table 42 and having good safety.

[0037] A second horizontal tie rod 46 and two crossed diagonal tie rods 43 are connected between two legs 41 at the symmetric positions of the two Euro bins 3. A first horizontal tie rod 45 is connected between two adjacent legs 41 on each Euro bin 3, improving the tensile strength of the metal gantry 4.

[0038] This embodiment provides a hoisting device for the maintenance of Euro bin equipment, which solves the hoisting requirements for the maintenance of equipment in adjacent two Euro bins 3, greatly facilitating the hoisting requirements during the maintenance and repair of the equipment in the Euro bin 3. Moreover, the monorail hoisting device is easy to repair, has extremely low use cost, can respond in real time, does not occupy ground space, and will not interfere with other equipment on site.

[0039] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
