Description

Technical Field

[0001] The invention relates to the technical field of crushing station equipment installation, and in particular to an installation method of a large-scale discharge hopper platform and an inclined wedge block for installation. Background Art

[0002] The crushing station is the main equipment in the mining area. Its function is to crush large pieces of raw ore into small pieces and then send them to the beneficiation area for fine processing through a belt conveyor. Among them, the unloading hopper platform is the main component of the crushing station. At present, the usual installation method of the unloading hopper platform is to first set up multiple supporting vertical beams at the bottom, then adjust the supporting vertical beams to the elevation position of the drawing and fix them, and then hoist multiple components for assembly, and then adjust the unloading hopper platform to meet the installation technical requirements of the drawing, and then weld and connect it to the pontoon legs. The above scheme involves a lot of high-altitude operations. Due to the high height, multiple supporting vertical beams are required for support, which greatly increases the material and labor costs.

[0003] Based on this, in order to reduce construction costs and reduce the workload of high-altitude installation, the existing technology generally chooses to place multiple components of the unloading hopper platform on the ground for welding and assembly. After being welded into a whole, the entire unloading hopper platform is hoisted to the top of the pontoon by a crawler crane and welded to the pontoon.

[0004] However, due to the large size and heavy tonnage of the unloading hopper platform, high installation precision is required. During the hoisting process, there will be a certain degree of swing, and it is difficult to ensure a good landing position during hoisting, which is prone to inaccurate positioning. Then it is difficult to adjust after positioning. On the other hand, the bottom of the unloading hopper platform also needs to be connected to the conveying structure to ensure that all materials can fall onto the conveyor belt. The crusher support frame and other structures need to be installed above the unloading hopper. Therefore, the unloading hopper platform also has high installation precision requirements.

[0005] Therefore, there is an urgent need for a method for installing a discharge hopper platform that can ensure the installation accuracy of the discharge hopper platform and is simple and easy to implement. Summary of the invention

[0006] The purpose of this application is to solve the problem of difficulty in positioning the unloading hopper platform during installation in the prior art. Therefore, the present invention provides an installation method for a large unloading hopper platform and an inclined wedge block for installation. The pontoon legs are supported by a plurality of wedge blocks arranged at the bottom of the unloading hopper platform to guide the unloading hopper platform into a designated position and compensate for the swing of the unloading hopper platform during the hoisting process. The cost is low and the operation is simple. After practical operation, the measurement data error after positioning is small, which meets the installation technical requirements and has been well applied.

[0007] To achieve the above-mentioned object, in a first aspect, the present invention provides an inclined wedge block for installing a large discharge hopper platform, wherein the inclined wedge block is arranged at the bottom of the discharge hopper platform;

[0008] The inclined wedge block includes a connecting surface, a bearing surface and a contact surface, wherein the connecting surface is fixed to the lower surface of the discharge hopper platform, and the bearing surface is inclined. During the descending process of the discharge hopper platform, the bearing surface contacts the edge of the contact pontoon leg and guides the discharge hopper platform to slide along the bearing surface toward the contact surface.

[0009] The shape of the abutment surface corresponds to the side surface of the floating bridge leg;

[0010] After the lower surface of the discharge hopper platform is in contact with the upper surface of the floating bridge leg, the abutment surface is in contact with the side surface of the floating bridge leg.

[0011] With the above solution, the inclined wedge block plays a guiding and positioning role in the installation of the discharge hopper platform, helping the discharge hopper platform to be accurately installed on the floating bridge leg. The entire inclined wedge block has a simple structure and is easy to manufacture. The wedge block is easy and flexible to use, and can be used with different types of supports. It can be set according to the shape and position of the support (floating bridge leg) on ​​site; its width and length can be designed according to the construction conditions on site and the weight of the discharge hopper platform, and it is flexible to use and easy to manufacture.

[0012] In some embodiments, the inclined wedge block also includes two parallel side surfaces, and the side surfaces are right-angled trapezoids; the height of the right-angled trapezoid is located at the connecting surface, the upper base of the right-angled trapezoid is located at the contact surface, and the hypotenuse of the right-angled trapezoid is located at the receiving surface.

[0013] With such arrangement, the shape of the inclined wedge is more regular, and it is convenient to manufacture and process.

[0014] In a second aspect, the present invention provides a method for installing a large unloading hopper platform, using the above-mentioned inclined wedge block for installing a large unloading hopper platform, the steps of which include:

[0015] S1: Measure the positions of multiple pontoon legs and the distances between multiple pontoon legs;

[0016] S2: making a plurality of longitudinally positioned longitudinally inclined wedges and a plurality of transversely positioned transversely inclined wedges;

[0017] S3: Marking the bottom of the discharge hopper platform according to the position of the floating bridge legs;

[0018] S4: fixing the inclined wedge block to the bottom of the discharge hopper platform according to the marked position, the contact surface of the longitudinal inclined wedge block corresponds to the longitudinal surface of the floating bridge leg, limiting the longitudinal position of the discharge hopper platform; the contact surface of the transverse inclined wedge block corresponds to the transverse surface of the floating bridge leg, limiting the transverse position of the discharge hopper platform;

[0019] S5: hoisting the discharge hopper platform into place;

[0020] S6: Use a total station to measure the unloading hopper platform. The measurement data should meet the technical requirements of the drawings;

[0021] S7: Select welding rods that match the parent material to weld the unloading hopper platform and the pontoon legs.

[0022] It should be noted that in the actual process, there are multiple pontoon legs, and the positions of the multiple pontoon legs are not easy to determine. Therefore, the present application measures the spacing between the multiple pontoon legs after the pontoon legs are placed, and draws lines on the lower surface of the discharge hopper platform according to the relative positions of the pontoon legs. Then, the inclined wedges are welded to the bottom of the discharge hopper platform according to the positions of the pontoon legs. With such an installation sequence, the installation is more accurate. On the other hand, multiple inclined wedges are set at the bottom of the discharge hopper platform. Even if the suspended discharge hopper platform swings in the air, as long as the swing range does not exceed the projection range of the receiving surface of the inclined wedge, during the descent of the discharge hopper platform, the receiving surface of the inclined wedge will first contact the pontoon legs and guide the discharge hopper platform to move, and then return the discharge hopper platform to its normal installation position.

[0023] In some embodiments, a plurality of the longitudinal oblique wedges are symmetrically arranged on two surfaces in the longitudinal direction of the floating bridge legs;

[0024] The plurality of transverse inclined wedge blocks are symmetrically arranged on two transverse surfaces of the floating bridge legs.

[0025] With the above solution, symmetrical inclined wedges are provided on both surfaces of the pontoon legs in the longitudinal direction, so that the symmetrical inclined wedges clamp the pontoon legs from both sides, so that the movement of the pontoon legs in both directions in the longitudinal direction can be within the projection range of the inclined wedges, and the discharge hopper platform can be guided to the designated position. The same principle applies in the longitudinal direction.

[0026] In some embodiments, at least 4 of the longitudinal diagonal wedges and at least 4 of the transverse diagonal wedges are included;

[0027] On a transverse surface of the floating bridge leg, there are no less than two transverse oblique wedge blocks;

[0028] At least two longitudinal oblique wedge blocks are distributed on a longitudinal surface of the floating bridge leg.

[0029] By adopting the above scheme, the two inclined wedge blocks are respectively located at the two ends of the discharge hopper platform, which increases the contact position between the supporting surface of the inclined wedge block and the floating bridge leg, reduces the pressure received by a single inclined wedge block, makes the support smoother, and increases the projection area of ​​the supporting surface of the inclined wedge block. When the discharge hopper platform deflects at some angles, the inclined wedge block can also contact the floating bridge leg.

[0030] In some embodiments, the floating bridge legs are four and are supported at four end points of the bottom of the discharge hopper platform respectively; each of the floating bridge legs includes an inner surface close to the center position of the discharge hopper platform and an outer surface close to the edge position of the discharge hopper platform;

[0031] The longitudinal inclined wedge block is arranged on the inner surface of the floating bridge leg, and the transverse inclined wedge block is arranged on the outer surface of the floating bridge leg;

[0032] Or the longitudinal inclined wedge block is arranged on the outer surface of the floating bridge leg, and the transverse inclined wedge block is arranged on the inner surface of the floating bridge leg.

[0033] The position and number of the inclined wedges can be flexibly set according to the number and position of the pontoon legs. In this way, the bearing surfaces in the transverse and longitudinal inclined wedges are oriented one inward and one outward respectively. This is more suitable for the situation of multiple pontoon legs and can better clamp the pontoon legs. Relative to the pontoon legs as a whole, in this way, the force of the inclined wedges is applied to the outer surface and the inner surface respectively, and the position of the force is more dispersed, which is more conducive to the stability of the overall structure.

[0034] In some embodiments, when installing the angled wedge block, a gap of 2 mm should be reserved between the abutment surface and the side surface of the floating bridge leg.

[0035] The error caused by measurement and welding is balanced. It should be noted that the error is about 3mm, which meets the installation requirements. This setting leaves a certain amount of redundancy to prevent the wedge block from being unable to align with the pontoon leg due to measurement error or installation error.

[0036] In general, compared with the prior art, the beneficial effects of the present invention are as follows: the unloading hopper platform is limited and guided by the inclined wedge block, so that the unloading hopper platform can be installed in the specified position even under a certain swinging condition, avoiding the problem of inaccurate positioning of the unloading hopper platform and difficulty in adjustment after it is in place. In addition, the installation method of the present invention is simple to operate, low in cost, labor-saving, time-saving and labor-saving; it is applicable to a variety of pontoon legs, and can be adaptively adjusted according to the number, shape and position of the pontoon legs.

[0037] Other features and corresponding beneficial effects of the present application are described in the latter part of the specification, and it should be understood that at least some of the beneficial effects become obvious from the records in the specification of the present application.

[0049] Example

[0050] See also Figure 1, this embodiment provides an inclined wedge block for installing a large discharge hopper platform, and the inclined wedge block 1 is arranged at the bottom of the discharge hopper platform 2;

[0051] The inclined wedge block 1 includes a connecting surface 11, a receiving surface 12 and a contact surface 13. The connecting surface 11 is fixed to the lower surface of the discharge hopper platform 2, and the receiving surface 12 is inclined. During the descending process of the discharge hopper platform 2, the receiving surface 12 contacts the edge of the contact pontoon leg 3 and guides the discharge hopper platform 2 to slide along the receiving surface 12 to the contact surface 13.

[0052] The shape of the abutment surface 13 corresponds to the side surface of the floating bridge leg 3;

[0053] After the lower surface of the discharge hopper platform 2 is in contact with the upper surface of the floating bridge leg 3 , the abutment surface 13 is in contact with the side surface of the floating bridge leg 3 .

[0054] In the prior art, there is a lack of means for adjusting the position of the heavy-weight discharge hopper platform, so the position of the discharge hopper platform 2 can generally only be adjusted by pulling ropes during the lifting process; the solution of the present application guides the position of the discharge hopper platform 2 through an inclined wedge block 1 connected to the bottom of the discharge hopper platform 2. The wedge block is guided by the supporting surface 12 so that the resistance surface 13 fits with the side of the pontoon leg 3, thereby realizing the precise installation of the discharge hopper platform 2.

[0055] For details, see Figure 2-5 In this embodiment, there are 4 floating bridge legs 3, with 8 identical inclined wedges 1, and the inclined wedges 1 include two mutually parallel side surfaces, and the side surfaces are right-angled trapezoids; the height of the right-angled trapezoid is located at the connecting surface 11, the upper bottom of the right-angled trapezoid is located at the abutting surface 13, and the hypotenuse of the right-angled trapezoid is located at the receiving surface 12. Specifically, the inclined wedges 1 are set at the bottom of the discharge hopper platform 2 by welding.

[0056] The four floating bridge legs 3 are supported at four end points of the bottom of the discharge hopper platform 2 respectively; each floating bridge leg 3 includes an inner surface close to the center position of the discharge hopper platform 2 and an outer surface close to the edge position of the discharge hopper platform 2.

[0057] In addition, this embodiment also provides a method for installing a large unloading hopper platform, using the above-mentioned inclined wedge block for installing a large unloading hopper platform. Taking the unloading hopper platform as an example, the steps include:

[0058] Step 1: First, adjust two floating bridges according to the technical requirements of the drawings, and set four floating bridge legs on the two floating bridges;

[0059] Step 2: Select a suitable site for assembling the unloading hopper platform; (the site selection must ensure that it meets the performance requirements of the crawler crane, because the maximum lifting weight of the crawler crane is not allowed to exceed 70% of the rated maximum lifting weight);

[0060] Step 3: Lift multiple parts of the unloading hopper platform and set pads (blocks) at the bottom;

[0061] Step 4: Connect, assemble and adjust the unloading hopper platform to the technical requirements of the drawings;

[0062] Step 5: Select welding rods that match the base material to weld the interface of the discharge hopper platform;

[0063] Step 6: Follow Figure 1 Producing a plurality of longitudinally positioned longitudinally inclined wedges and a plurality of transversely positioned transversely inclined wedges;

[0064] Step 7: Measure the actual size and position of the four floating bridge legs (3) and the spacing between the multiple floating bridge legs (3);

[0065] Step 8: Mark the position of the inclined wedge (1) on the discharge hopper platform according to the position of the floating bridge legs (3);

[0066] Step 9; see Figure 2 , eight inclined wedge blocks (1) are welded according to the marked positions, the contact surface (13) of the longitudinal inclined wedge block corresponds to the longitudinal surface of the floating bridge leg (3), thereby limiting the longitudinal position of the discharge hopper platform (2); the contact surface (13) of the transverse inclined wedge block corresponds to the transverse surface of the floating bridge leg (3), thereby limiting the transverse position of the discharge hopper platform (2);

[0067] Step 10: Use crawler crane to hoist the unloading hopper platform into place;

[0068] Step 11: Use a total station to measure the unloading hopper platform. The measurement data should meet the technical requirements of the drawings;

[0069] Step 12: Select welding rods that match the parent material for welding the hopper platform and the pontoon legs.

[0070] When there is no disturbance at all during lifting, the contact surface 13 of the wedge block is in contact with the side of the pontoon leg 3. When shaking occurs during lifting and the discharge hopper platform 2 swings, the contact surface 13 of the inclined wedge block 1 cannot correspond to the side of the pontoon leg 3. However, an inclined supporting surface 12 is provided on the inclined wedge block 1, and the supporting surface 12 is connected to the contact surface 13. Therefore, even if the discharge hopper platform 2 shakes, as long as the shaking does not exceed the projection range of the supporting surface 12, the supporting surface 12 can first contact with the edge of the upper surface of the pontoon leg 3 during the descent of the discharge hopper platform 2, and the discharge hopper platform 2 descends along the supporting surface 12, guiding the contact surface 13 to the side of the pontoon leg 3, and finally making the contact surface 13 fit with the side of the pontoon leg 3, so that the entire discharge hopper platform 2 is installed to the specified position.

[0071] Specifically, in the present embodiment, the eight inclined wedge blocks 1 are divided into four longitudinal inclined wedge blocks 1 and four transverse inclined wedge blocks 1. After drawing lines at the bottom of the discharge hopper platform 2 according to the positions of the pontoon legs 3, the four longitudinal inclined wedge blocks 1 are respectively arranged to correspond to the positions of the four pontoon legs 3, with their receiving surfaces 12 facing outward, and are symmetrically arranged on the two longitudinal surfaces of the pontoon legs 3; the four transverse inclined wedge blocks 1 are respectively arranged to correspond to the positions of the four pontoon legs 3, with their receiving surfaces 12 facing inward, and are symmetrically arranged on the two transverse surfaces of the pontoon legs 3; making the setting positions of the inclined wedge blocks 1 more dispersed is more conducive to the balance of the overall structure.

[0072] Specifically, the pontoon legs are four, which are supported at four end points of the bottom of the discharge hopper platform respectively; each pontoon leg includes an inner surface close to the center of the discharge hopper platform and an outer surface close to the edge of the discharge hopper platform; specifically, the pontoon legs are in the shape of "earth".

[0073] In some implementations, the longitudinally inclined wedges are disposed on the inner surfaces of the floating bridge legs, and the transversely inclined wedges are disposed on the outer surfaces of the floating bridge legs.

[0074] In some implementations, the longitudinal oblique wedge block is disposed on an outer surface of the floating bridge leg, and the transverse oblique wedge block is disposed on an inner surface of the floating bridge leg.

[0075] Specifically, after measuring the spacing between two relative inclined wedge blocks 1, it is necessary to make a 2mm adjustment on this basis, increasing the spacing of the horizontal inclined wedge blocks 1 and reducing the spacing of the longitudinal inclined wedge blocks 1, thereby avoiding measurement errors and leaving a certain amount of redundancy to prevent the inclined wedge blocks 1 from being unable to align to the specified position due to measurement errors or slightly larger swings.
