Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyor installation, and in particular relates to an installation method for an ultra-long belt conveyor in a complex environment. Background Art

[0002] In the construction field, in order to save space, the belt conveyor for conveying materials is usually set in the longitudinal space covering the multi-layer platform. At the same time, the belt conveyor is long, and the head and tail equipment are arranged closely. In this way, the belt conveyor at the top is difficult to construct due to height and space limitations. In order to reduce the number of joints in the construction of the tape and increase the service life of the tape, the tape of the super-long tape machine is a roll of glasses, about 600 meters long and weighing about 30 tons. The two rolls of belts are symmetrically distributed. One roll needs to be spit out in advance. A roll of tape is about 300 meters long. After spitting out, a large area of ​​​​space is required for the threading work. At the same time, because the tape is heavy, it is very difficult to move without a crane. A crane with a large rated load is required to cooperate in lifting it to the high-rise installation position. The large crane has a high shift cost, especially the replacement of the tape after production, which has a greater workload. The walls around the transfer station have been closed, and a large area of ​​​​the wall needs to be removed to lift the roll of glasses The tape is in place, and the removal cost is high.

[0003] The traditional method of threading a belt conveyor is to make a set of tape support frames, use a crane to place the support frames in a spacious position at the head or tail of the belt conveyor, then place the tape roll on top of the support frames, and the tape can rotate on the support frames. Finally, a winch or other machinery is used to thread the tape. There is an existing belt conveyor installation method for an installation environment with a large vertical height. The Chinese invention patent with application number CN202011349239.1 discloses a method for installing an ultra-high vertical feeding belt conveyor, including formulating an operation sequence for entering the site, hoisting and installing each part of the head part, vertical section part, tail part and belt part of the belt conveyor; the formulated process flow performs hoisting operations on the head part of the belt conveyor; installation of the vertical belt; lifting the belt; installation of the head and tail; and belt threading and installation of redirecting rollers, pressure wheels, etc. However, the method divides the belt too finely, involves a complex auxiliary installation structure, and has cumbersome steps. The sections of the belt may affect each other and cause offsets, increasing the difficulty of operation for workers. The installation method itself is greatly affected by the installation site, and the vertical section may be difficult to install due to structural interference from other objects in the belt threading space. It is difficult for workers to change flexibly when faced with a complex environment.

[0004] Therefore, there is an urgent need for an installation method for an ultra-long belt conveyor in a complex environment that involves a simple auxiliary structure, uncomplicated steps, low difficulty in installation and replacement, little impact from the site, and the ability to flexibly change according to actual conditions. Summary of the invention

[0005] The object of the present invention is to provide a method for installing an ultra-long belt conveyor in a complex environment in view of the deficiencies of the prior art, aiming to solve the problems existing in the existing belt conveyor installation methods, such as complex auxiliary installation structures, cumbersome steps, being greatly affected by the complex installation site conditions, being difficult to perform vertical installation due to interference from other object structures in the environment, and being difficult to flexibly transform according to the actual situation.

[0006] To solve the above technical problems, the present invention provides a method for installing an ultra-long belt conveyor in a complex environment, including:

[0007] Install a winch on the lower platform at the belt conveyor installation position, lift the belt conveyor components except the belt to the belt conveyor installation position and complete the preliminary installation, hoist the spectacle roll belt and the support frame below the building hoisting hole, determine the preset path through which the belt passes in the longitudinal space according to the actual installation environment, pass the steel wire rope of the winch over the lower idlers of the belt conveyor and then successively pass outside the deflecting rollers at both ends of the belt conveyor to form an inverted U shape, and then reach the belt along the preset path, connect one end of the steel wire rope and the belt, start the winch to thread the belt, and connect the two ends of the belt after threading is completed.

[0008] In some embodiments, it includes the following steps:

[0009] S1. Make a belt support frame according to the actual length and width of the belt, make a guide roller according to the actual accommodation space of the threading environment, and make a belt clamp according to the specifications of the belt and the steel wire rope;

[0010] S2. Fix the winch on the lower platform at the belt conveyor installation position, lift the belt conveyor components except the belt to the belt conveyor installation position and complete the preliminary installation;

[0011] S3. Move the support frame with the spectacle roll belt to below the belt conveyor installation position, and determine the preset path for threading according to the actual longitudinal space environment between the belt position and the belt conveyor installation position;

[0012] S4. Cut a threading hole on the platform that needs to be passed through according to the preset path, and install a guide roller at the turning point;

[0013] S5. Pass the steel wire rope of the winch through the topmost platform to reach the lower idlers of the belt conveyor, successively pass through and closely adhere to the outside of the deflecting rollers at both ends of the belt conveyor to form an inverted U shape, and then reach the belt along the preset path;

[0014] S6. Use the belt clamp to connect one end of the steel wire rope and the belt, start the winch to perform the threading work, and vulcanize and connect the head and tail ends of the belt after threading is completed to complete the installation of the belt conveyor.

[0015] In some embodiments, in S3, the spectacle roll tape and the support frame are hoisted below the building hoisting hole. The crane is used to unwind the first roll of the spectacle roll and stack it neatly on the ground. Another roll is placed on the support frame. In S6, after one spectacle roll is threaded, the other spectacle roll tape is threaded in the same way, and then the joints of the two spectacle rolls are heated and vulcanized to be connected into one tape.

[0016] In some embodiments, in S5, the steel wire rope starts from below the nearby redirecting roller, winds around the outer side of the far redirecting roller for half a circle and returns above the nearby redirecting roller, and then passes through the guiding roller on the topmost platform and reaches the tape along the preset path.

[0017] Further, in some embodiments, in S5, the wire rope passes through the rope-passing hole on the topmost platform and the tape-passing hole on the topmost platform in the preset path, which is the same perforation.

[0018] Further, in some embodiments, in S3 and S5, the preset path starts from the tape position and ends at the tape-passing hole on the topmost platform. The wire rope reaches the tape position from the tape-passing hole on the topmost platform along the reverse direction of the preset path.

[0019] In some embodiments, the number of guiding rollers is not less than three.

[0020] In some embodiments, the tape clamp is a pair of tape clamping plates fixedly installed by bolts.

[0021] In some embodiments, the spectacle roll tape is rotatable on the support frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The installation method of the ultra-long belt conveyor in a complex environment provided by the present invention simply divides the installation space into a lower space, an upper space and a middle space. By setting the preset path for threading the tape, the tape connects the three spaces. The support frame, guiding rollers and tape clamps are set to assist the threading work, and the threading work is completed by the traction of the winch, enabling workers to flexibly change the preset path according to the actual complex environment, and at the same time, being able to flexibly change the operation means according to the actual environment in each space. The installation process has less requirements for the site space, only requiring the longitudinal positions of each space to be close. It simplifies the installation steps and auxiliary structures, improves the operability and operation flexibility of the installation process, and reduces the construction difficulty.

[0024] 2. The installation method of the ultra-long belt conveyor in a complex environment provided by the present invention compresses the threading space into a narrow space that only needs to accommodate the tape and guiding rollers, making the overall installation process less affected by the surrounding environment and having less impact on the surrounding environment, and avoiding the construction from being unable to proceed due to the structural interference of other items in the space.

[0025] 3. After installation, the replacement of the tape is more convenient and quick. You only need to replace the tape according to the tape holes left during installation. There is no need to demolish the walls around the building, which saves a lot of work and reduces the difficulty of replacement.

[0026] 4. There is no need for a large-tonnage crane to lift it to the high-rise frame installation position. You only need to use a crane to place the tape on the ground below the lifting hole, saving the cost of a large crane. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0035] The present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0036] The present invention provides a method for installing an ultra-long belt conveyor in a complex environment, comprising:

[0037] Install the winch 2 on the platform below the belt conveyor installation position, lift the belt conveyor components except the tape 1 to the belt conveyor installation position and complete the preliminary installation, hoist the eyeglass roll tape 1 and the support frame 3 to the bottom of the building's hoisting hole, and determine the preset path for the tape 1 to pass through in the longitudinal space according to the actual installation environment. Pass the steel wire rope 201 of the winch 2 on the lower roller 601 of the belt conveyor through the outer side of the redirecting roller 602 at both ends of the belt conveyor in sequence to form an inverted U shape, and then reach the tape 1 along the preset path, connect the steel wire rope 201 and one end of the tape 1, start the winch 2 to thread the tape, and connect the two end joints of the tape 1 after the threading is completed.

[0038] like Figures 1 to 5 As shown, the present invention simply divides the installation space into a lower space, an upper space and a middle space, and sets a preset path for threading the tape so that the tape 1 connects the three spaces, and compresses the threading space into a narrow space that only needs to accommodate the tape 1 and the guide roller 4, and uses the winch 2 to pull and complete the threading work. The overall installation process is less affected by the surrounding environment and has less impact on the surrounding environment, and the construction is prevented from being unable to proceed due to structural interference of other objects in the space. Workers can flexibly change the preset path according to the actual complex environment, and can flexibly change the operating means according to the actual environment in each space. The installation process has less requirements on the site space. It is only necessary that the longitudinal positions of each space are similar, which simplifies the installation steps and auxiliary structures, improves the operability and flexibility of the installation process, reduces the construction difficulty, and makes the replacement of the tape 1 after installation more convenient and quick. It is only necessary to replace the tape 1 according to the preset path left during installation, and there is no need to demolish the walls around the building, which saves a lot of work and reduces the difficulty of replacement. There is no need for a large-tonnage crane to cooperate in lifting to the high-rise frame installation position. It is only necessary to use a crane to place the tape 1 on the ground below the lifting hole, which saves the cost of a large crane. Among them, the lower space can use a space with a larger open space to facilitate the transportation of the glasses roll tape 1.

[0039] In some embodiments, the steps include:

[0040] S1, making a support frame 3 for the adhesive tape 1 according to the actual length and width of the adhesive tape 1, making a guide roller 4 according to the actual accommodation space of the tape threading environment, and making a clamp for the adhesive tape 1 according to the specifications of the adhesive tape 1 and the steel wire rope 201;

[0041] S2. Fix the winch 2 on the platform below the belt conveyor installation position, lift the belt conveyor components except the belt 1 to the belt conveyor installation position and complete the preliminary installation;

[0042] S3, moving the support frame 3 with the eyeglass roll tape 1 to the bottom of the belt conveyor installation position, and determining the preset path for threading the tape according to the actual longitudinal space environment between the tape 1 and the belt conveyor installation position;

[0043] S4. Cut a tape-passing hole on the platform to be passed through according to the preset path, and install a guiding roller 4 at the site where turning is required;

[0044] S5. Pass the steel wire rope 201 of the winch 2 through the topmost platform to reach the lower idler 601 of the belt conveyor, successively pass through and closely adhere to the outer sides of the redirecting rollers 602 at both ends of the belt conveyor to form an inverted U shape, and then reach the tape 1 along the preset path;

[0045] S6. Use the tape 1 clamp to connect the steel wire rope 201 and one end of the tape 1, start the winch 2 to perform the tape-passing work, and after the tape-passing is completed, vulcanize and connect the head and tail ends of the tape 1 to complete the installation of the belt conveyor.

[0046] In some specific extended embodiments, in S3, hoist the spectacle roll tape 1 and the support frame 3 below the building hoisting hole, use a crane to unwind the first roll of the spectacle roll, neatly stack it on the ground, and place the other roll on the support frame 3 to facilitate the traction of the tape by the steel wire rope and reduce the load of the winch. In S6, when the tape-passing of one spectacle roll is completed, pass the tape of the other spectacle roll in the same way, and then heat and vulcanize the joints of the two spectacle rolls to connect them into a tape 1.

[0047] In some preferred embodiments, in S5, the steel wire rope 201 starts from below the nearby redirecting roller 602, winds around the outer side of the distant redirecting roller 602 for half a circle and returns above the nearby redirecting roller 602 to form an inverted U shape on the belt conveyor assembly 6, and then passes through the guiding roller 4 on the topmost platform and reaches the tape 1 along the preset path. During the process of being traction-passed through the tape, the tape 1 completes the movement in the longitudinal space and the passing-through installation on the belt conveyor assembly 6, simplifying the installation process.

[0048] In some specific extended embodiments, in S5, the wire-passing hole of the topmost platform and the tape-passing hole of the topmost platform on the preset path through which the steel wire rope 201 passes are both arranged close to the redirecting roller 602 at one end of the belt conveyor. Use the already fixedly installed belt conveyor assembly 6 as an auxiliary structure for the horizontal traction of the tape 1 on the topmost platform to facilitate the steel wire rope 201 to traction the tape 1 to complete the passing-through installation on the belt conveyor assembly 6 on the topmost platform.

[0049] In some specific extended embodiments, in S5, the wire-passing hole of the topmost platform and the tape-passing hole of the topmost platform on the preset path through which the steel wire rope 201 passes are the same perforation. The guiding roller 4 on the topmost platform makes the tape 1 in the tape-passing hole close to one side of the perforation, and the winch 2 is preferably arranged as close as possible below the belt conveyor assembly 6 to make the steel wire rope 201 close to the other side of the perforation, so that the steel wire rope 201 and the tape 1 can share one perforation, reducing the adverse impact of repeated drilling on the stability of the platform.

[0050] In some specific extended embodiments, in S3 and S5, the preset path starts from the tape 1 and ends at the tape threading hole of the uppermost platform, and the wire rope 201 reaches the tape 1 from the tape threading hole of the uppermost platform in the opposite direction along the preset path. In this way, in the process of the wire rope 201 pulling the tape 1, that is, in the process of the winch 2 recovering the wire rope 201, the tape 1 will be threaded along the preset direction of the preset path, and the space occupied by the threading will be converted from a larger overall longitudinal space to a narrower threading space that only needs to accommodate the tape 1 and the guide roller 4. Workers can design targeted preset paths and install guide rollers 4 according to the actual construction environment, thereby improving the operability and flexibility of the threading process.

[0051] In some specific extended embodiments, the number of guide rollers 4 is not less than three, such as Figure 1 As shown, the guide roller 4 serves to guide the adhesive tape 1 and the steel wire rope 201. The multiple guide rollers 4 at different heights divide the traction adhesive tape 1 into sections, so that the steel wire rope 201 of the winch 2 only bears part of the weight of the adhesive tape 1 with the help of support from other structures when traction of the adhesive tape 1. When there is space on some platforms for laying the adhesive tape 1, the multiple guide rollers 4 at the same height can also provide support for part of the adhesive tape 1, further reducing the operating load of the winch 2.

[0052] In some specific extended embodiments, the tape 1 clamp is a pair of tape 1 clamps fixedly installed by bolts, such as Figure 5 As shown, the tape 1 clamp is arranged on both sides of one end of the tape 1, and the installation between the tape 1 clamp and the tape 1 is achieved by installing the bolts into the fastening bolt holes 502, and then one end of the wire rope 201 is installed on the tape 1 clamp to achieve the installation between the wire rope 201 and the tape 1.

[0053] In some specific extended embodiments, the eyeglass tape 1 can be rotated on the support frame 3, such as Figure 2 and Figure 3 As shown, the central rod 303 is driven by an external motor to drive the adhesive tape 1 to rotate, and the two rolls of adhesive tape 1 rotate synchronously with the traction of the steel wire rope 201, further reducing the floor space occupied by the adhesive tape 1.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the specification of the present invention should be included in the protection scope of the present invention.
