Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to a reverse installation device and an installation method for a sintering machine trolley. Background Art

[0002] The sintering machine is composed of a frame, a head driving device, a head star wheel, a head curved rail, an upper rail, a tail star wheel, a tail curved rail, a lower rail, a feeding system, an ignition system, a bellows and a sintering trolley. Among them, the sintering trolley is the main operating equipment of the sintering machine. Its main function is to transport the sintering mixture to the ignition furnace through the upper horizontal rail for ignition, and then transport the sintered block to the sintering tail guide box. After turning the material, it returns to the head wheel through the lower horizontal rail, and realizes the entire sintering cycle by making continuous circular motion along the elliptical track. Therefore, the installation quality and installation progress of the sintering machine trolley directly affect the commissioning and operation of the sintering production line.

[0003] The conventional method of installing a sintering machine trolley is to use a workshop crane to first install part of the trolley on the lower track after the frame, upper track and lower track are installed and before the tail star wheel is installed, and then install the head and tail equipment of the sintering machine and then install the trolley on the upper track; or adopt a forward installation method, first after the sintering equipment is installed and accepted, use a workshop crane to install the sintering trolley from the upper track, so that it flips from the tail curved track to the lower track; because the tail star wheel is not equipped with a driving device, when the above two methods are used for installation, the trolley will flip downward under the action of its own gravity after engaging with the tail star wheel, which is the phenomenon of trolley slipping. The trolley will collide with the previous trolley installed on the lower track, which is easy to cause safety accidents or equipment damage. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a sintering machine trolley reverse installation device and installation method, which realizes the rapid and lossless installation of the trolley and improves the installation efficiency of the trolley.

[0018] Start the hoisting mechanism and drive the trolley group closest to the head curved rail to move in the direction of the head curved rail through the traction rope;

[0019] When the first trolley of the trolley group closest to the head curved rail enters the head curved rail, the hoisting mechanism is stopped to make the clamping wheel of the first trolley mesh with the head star wheel;

[0039] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, a sintering machine trolley reverse installation device of the present invention comprises: a sintering machine, a crane mechanism 12 and a hoisting mechanism 10, wherein the sintering machine comprises a head driving device 4, a head star wheel 3, a head curved rail 2, an upper rail 5, a tail star wheel 7, a tail curved rail 8 and a lower rail 6 which have been installed; the head driving device 4 drives the head star wheel 3 to rotate in the opposite direction; the crane mechanism 12 is erected above the sintering machine, and is used to place the trolley 11 on the upper rail 5; the hoisting mechanism 10 is arranged in front of the sintering machine head, aligned with the center line of the upper rail 5, and is used to connect the trolley 11 on the upper rail 5.

[0041] The above-mentioned sintering machine includes a sintering frame 1 and a head driving device 4, a head star wheel 3, a head curved rail 2, an upper horizontal rail, a tail star wheel 7, a tail curved rail 8, a lower horizontal rail, a feeding system, an ignition system, a bellows and a sealing cover installed on the sintering frame 1, wherein the head curved rail 2, the upper rail 5, the tail curved rail 8 and the lower rail 6 are connected in sequence to form an elliptical rail, and a number of trolleys 11 are engaged with the rails. When the sintering machine is in use, the head driving device 4 causes the head star wheel 3 to rotate, driving the trolley 11 engaged with the head star wheel 3 to run along the head curved rail 2 to the upper rail 5, and then pushing the trolley 11 on the upper rail 5 to run repeatedly along the motion trajectory of the tail curved rail 8-lower rail 6-head curved rail 2.

[0042] In the present application, the head driving device 4, the head star wheel 3, the head curved rail 2, the upper rail 5, the tail star wheel 7, the tail curved rail 8 and the lower rail 6 on the sintering machine are used in cooperation with the hoisting mechanism 10 and the traveling mechanism 12 to realize the installation of the trolley 11; in this process, there is no restriction on the installation status of other components of the sintering machine, and the installation can be completed before the installation of the trolley 11 or after the installation of the trolley 11 is completed as needed, so that the installation of the trolley 11 will not affect other equipment, thereby greatly improving the installation efficiency of the equipment.

[0043] By utilizing the cooperation between the winch mechanism 10 and the head drive device 4, the trolley 11 can enter the lower track 6 along the head curved rail 2, thereby realizing the reverse installation of the trolley 11. Compared with the prior art in which the trolley 11 enters the lower horizontal track from the tail curved rail 8, the trolley 11 will not slip, and collisions between the trolleys 11 installed successively to cause damage to the equipment are avoided. At the same time, the installation operation is simple, fast, safe, reliable, and practical, which greatly improves the installation efficiency of the trolley 11.

[0044] Furthermore, a plurality of groups of trolleys 11 are installed on the upper rail 5 , and each group of trolleys 11 is fitted together to form a trolley group; the traction rope 101 of the hoisting mechanism 10 is connected to the trolley group closest to the head curved rail 2 .

[0045] Specifically, each group of trolleys 11 fits together, and adjacent trolley groups can fit together or be spaced apart; the traction rope 101 of the hoisting mechanism 10 drives the trolley group closest to the head curved rail 2 to move in the direction of the head curved rail 2. After the installation of the trolley group is completed, the traction rope 101 of the hoisting mechanism 10 is connected to the trolley group closest to the head curved rail 2 among the remaining trolley groups, so that the trolley groups arranged in the direction from the head curved rail 2 to the tail curved rail 8 are installed in sequence, thereby improving the efficiency of the installation of the trolleys 11. Preferably, the number of trolleys 11 included in each trolley group can be set in accordance with the model of the hoisting mechanism 10 to improve the installation efficiency of the trolleys 11.

[0046] Furthermore, the traction rope 101 is connected to the last trolley 11 of the trolley group closest to the head curved rail 2. When in use, the hoisting mechanism 10 is started to drive the trolley group to approach the head curved rail 2. When the first trolley 11 of the trolley group enters the head curved rail 2, the hoisting mechanism 10 is stopped, the head driving device 4 is started, and the first trolley 11 is driven to enter the lower track 6 along the head curved rail 2 through the rotation of the head star wheel 3. The hoisting mechanism 10 is opened again and the above operation is repeated to install the next trolley 11. After the last trolley 11 enters the head curved rail 2, the traction rope 101 is removed, and then the last trolley 11 is installed, thereby realizing the rapid installation of the trolley group.

[0047] Furthermore, a maintenance platform 9 corresponding to the height of the upper rail 5 is provided at the head of the sintering machine, and a hoisting mechanism 10 is detachably arranged on the maintenance platform 9. Specifically, the maintenance platform 9 is a supporting arrangement of the sintering machine, and is used to overhaul the sintering machine; in the present application, the maintenance platform 9 is arranged at a height corresponding to the upper rail 5, and the construction of the maintenance platform 9 is completed before the installation of the trolley 11, so as to facilitate the installation of the hoisting mechanism 10, so that the hoisting mechanism 10 is located on the extension line of the center of the sintering machine, and then the traction rope 101 can be extended in the horizontal direction to the trolley 11 installed on the upper rail 5, so as to facilitate the pulling of the trolley 11 without affecting other equipment; preferably, the maintenance platform 9 is pre-buried with a connector for installing the hoisting mechanism 10, so that the hoisting mechanism 10 can be conveniently and stably fixed to the maintenance platform 9, and the hoisting mechanism 10 can be removed after the trolley 11 is fully installed, which will not affect the normal use of the maintenance platform 9.

[0048] In a specific embodiment, a maintenance platform 9 corresponding to the height of the upper rail 5 and the lower rail 6 is arranged in front of the sintering machine head.

[0049] Furthermore, the traction rope 101 extends in the horizontal direction and is higher than the head star wheel 3, so as to ensure that the hoisting mechanism 10 and the head star wheel 3 can operate independently and will not affect each other and cause safety hazards.

[0050] Furthermore, a hook is provided at the free end of the traction rope 101, and the hook is connected to the rear side plate of the last trolley 11, so that the traction rope 101 can be easily connected to and removed from the trolley 11, thereby realizing the sequential and rapid connection of multiple trolley groups and improving the installation efficiency of the trolley 11.

[0051] The present application also proposes a method for reverse installation of a sintering machine trolley 11, using the reverse installation device for the sintering machine trolley 11 as described above, specifically comprising the following steps:

[0052] S1, such as Figure 1 As shown, the head driving device 4, the head star wheel 3, the head curved rail 2, the upper rail 5, the tail star wheel 7, the tail curved rail 8 and the lower rail 6 of the sintering machine are assembled to ensure that the head driving device 4, the head star wheel 3 and the tail star wheel 7 can operate normally; at the same time, the crane mechanism 12 is erected above the sintering machine, and the crane of the crane mechanism 12 can move along the direction of the upper rail 5.

[0053] In a specific embodiment, the feeding system, ignition system, wind box, sealing cover and other components of the sintering machine are also installed simultaneously.

[0054] S2, such as Figure 2 As shown, a plurality of trolleys 11 are placed on the upper track 5 through the traveling mechanism 12, and the trolleys 11 are installed on the upper track 5;

[0055] Specifically, a number of trolleys 11 form a trolley group, and the trolleys 11 in the same group fit tightly together. The trolley group can be fully distributed on the upper track 5 or a partial trolley group can be installed. As the trolleys 11 are installed one by one, the trolleys 11 on the upper track 5 gradually decrease, and the driving mechanism 12 lifts the new trolleys 11 to the upper track 5 one by one, and continuously adds new trolleys 11 to form a trolley group to facilitate continuous operation.

[0056] S3, install the hoisting mechanism 10 on the maintenance platform 9 corresponding to the upper track 5, and fix the traction rope 101 of the hoisting mechanism 10 on the last trolley 11 of the trolley group closest to the head curved rail 2 on the horizontal track;

[0057] Specifically, the hoisting mechanism 10 is installed on the extension line of the center of the sintering machine, and the traction rope 101 of the hoisting mechanism 10 extends in the horizontal direction, and the hook at the end of the traction rope 101 is connected to the rear side plate of the last trolley 11 of the trolley group closest to the head curved rail 2;

[0058] In a specific embodiment, the trolley group includes five trolleys 11, and the traction rope 101 is connected to the fifth trolley 11 of a trolley group each time.

[0059] S4, such as Figure 3 As shown, the hoisting mechanism 10 is started, and the trolley group closest to the head curved rail 2 is driven to move in the direction of the head curved rail 2 through the traction rope 101; preferably, the moving speed of the trolley group should not be too fast, so as to accurately control the installation of the trolley 11.

[0060] S5. When the first trolley 11 of the trolley group closest to the head curved rail 2 enters the head curved rail 2, the hoisting mechanism 10 is stopped to make the clamping wheel of the first trolley 11 engage with the head star wheel 3; specifically, when each clamping ring on both sides of the front of the first trolley 11 enters into a tooth groove of the tooth plates on both sides of the head star wheel 3, the hoisting mechanism 10 is stopped, and at this time, the other trolleys 11 of the trolley group are all located on the upper track 5.

[0061] S6, operating the head driving device 4 to make the head star wheel 3 rotate in the opposite direction, driving the first trolley 11 to move a set distance along the head curved rail 2, and then stopping the operation of the head star wheel 3;

[0062] Specifically, the set distance can be set as needed. It can be set to stop the head driving device 4 when the first trolley 11 leaves its initial position entering the head curved rail 2 so that the head curved rail 2 has space to accommodate another trolley 11; or stop the head driving device 4 when the first trolley 11 leaves the head curved rail 2 and enters the lower rail 6 to ensure that the head curved rail 2 has enough space to accommodate another trolley 11.

[0063] S7. Operate the hoisting mechanism 10, and when the second trolley 11 enters the head curved rail 2, stop operating the hoisting mechanism 10; alternately operate the head driving device 4 and the hoisting mechanism 10, until the last trolley 11 of the trolley group closest to the head curved rail 2 enters the head curved rail 2, untie the traction rope 101, operate the head driving device 4 to make the head star wheel 3 rotate in the opposite direction, and drive the last trolley 11 to enter the lower track 6.

[0064] Specifically, after untying the traction rope 101, the hoisting mechanism 10 is operated in the reverse direction, so that the traction rope 101 is reeled up to a position corresponding to the head curved rail 2, and then the head driving device 4 is operated to ensure the safe operation of the last trolley 11. In a specific embodiment, Figure 4 As shown, the trolley group includes five trolleys 11 , and at this time, all five trolleys 11 have entered the interior of the head curved rail 2 .

[0065] S8, such as Figure 5 As shown, the traction rope 101 is connected to the next trolley group, and the hoisting mechanism 10 and the head driving device 4 are operated alternately until the trolley 11 covers the lower track 6.

[0066] Specifically, when the next group of trolleys 11 is installed, with the rotation of the head star wheel 3, the previous group of trolleys 11 enters the lower track 6 along the head curved rail 2. Specifically, after the first trolley 11 of the previous group of trolleys 11 enters the lower track 6, the next trolley 11 also enters the lower track 6 driven by the head star wheel 3, and contacts the first step trolley 11, thereby pushing the first step trolley 11 to move along the lower track 6, and accordingly all the previous group of trolleys 11 enter the lower track 6; then the next group of trolleys 11 contacts the previous group of trolleys 11 and pushes the previous group of trolleys 11 to move along the lower track 6, and the adjacent trolleys 11 are in close contact with each other, and move toward the direction of the tail curved rail 8 under the push of the head star wheel 3 and the adjacent trolleys 11 until the lower track 6 is full of trolleys 11.

[0067] S9, such as Figure 6 As shown, after the trolleys 11 are fully distributed on the lower rail 6, the hoisting mechanism 10 and the head driving device 4 continue to operate alternately until the trolleys 11 are installed on the head curved rail 2, the lower rail 6 and the tail curved rail 8. At this time, the head curved rail 2, the lower rail 6 and the tail curved rail 8 are all fully distributed with trolleys 11, and the trolleys 11 are in close contact with each other; however, the upper rail 5 is not yet fully distributed with trolleys 11.

[0068] Specifically, the hoisting mechanism 10 and the head driving device 4 are repeatedly and alternately operated until some trolleys 11 pass through the tail curved rail 8 and enter the upper curved rail, and then the operation is stopped to ensure that the tail curved rail 8 is fully covered with trolleys 11 .

[0069] S10, such as Figure 7As shown, the trolleys 11 are installed one by one on the upper rail 5 through the driving mechanism 12 to fill the empty positions on the upper rail 5. At this time, the upper rail 5, the head curved rail 2, the lower rail 6 and the tail curved rail 8 are all fully installed with trolleys 11, and the installation of all trolleys 11 is completed.

[0070] The present invention uses the head driving device 4 of the sintering machine as the power, and utilizes the head star wheel 3, head curved rail 2, upper rail 5, tail star wheel 7, tail curved rail 8 and lower rail 6 of the equipment itself, in cooperation with the hoisting mechanism 10 and the traveling mechanism 12, to realize the reverse installation of the trolley 11; the overall operation is simple and fast, with high safety and easy control; it can not affect the installation of other equipment of the sintering machine, greatly shorten the installation time of the trolley 11, greatly improve the construction efficiency, and reduce the risk of damage to the trolley 11.

[0071] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
