Description

Technical Field

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

[0002] The sintering machine consists of a frame, head drive unit, head star wheel, head curved rail, upper rail, tail star wheel, tail curved rail, lower rail, feeding system, ignition system, bellows, and sintering trolley. The sintering trolley is the machine's primary operating equipment. Its primary function is to transport the sintering mixture via the upper horizontal rail to the ignition furnace for ignition. It then transports the sintered blocks to the sintering tail guide box. After turning the materials, it returns to the head wheel via the lower horizontal rail. This continuous circular motion along the elliptical track completes the entire sintering cycle. Therefore, the quality and speed of the sintering trolley installation directly impact the commissioning of the sintering production line.

[0003] The conventional method of installing a sintering machine trolley is to use a workshop crane to install part of the trolley on the lower track before installing the tail star wheel after the frame, upper track and lower track are installed, and then install the trolley on the upper track after installing the head and tail equipment of the sintering machine; or adopt a forward installation method, first install the sintering equipment after installation and acceptance, and then 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 drive device, when the above two installation methods are used, 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 may easily cause safety accidents or equipment damage. Utility Model Content

[0030] The above-mentioned sintering machine includes sintering machine frame 1 and the head drive device 4, head star wheel 3, head curved rail 2, upper horizontal rail, tail star wheel 7, tail curved rail 8, lower horizontal rail, feeding system, ignition system, air bellow and sealing cover etc. that are installed to sintering machine frame 1, wherein head curved rail 2, upper rail 5, tail curved rail 8 and lower rail 6 are sequentially connected to form an elliptical track, several trolleys 11 are connected with the track, when sintering machine is used, head drive device 4 makes head star wheel 3 rotate, drives trolley 11 meshing with head star wheel 3 to run along head curved rail 2 to upper rail 5, and then pushes trolley 11 on upper rail 5 to continuously circulate and repeatedly run along the movement track of tail curved rail 8-lower rail 6-head curved rail 2.

[0031] In this application, the head driving device 4, head star wheel 3, head curved rail 2, upper rail 5, tail star wheel 7, tail curved rail 8 and 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.

[0032] By utilizing the cooperation of 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, 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, causing 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.

[0033] Furthermore, a plurality 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 .

[0034] 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 toward 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 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.

[0035] 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 toward 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 along the head curved rail 2 into the lower track 6 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.

[0036] Furthermore, the sintering machine head is provided with a maintenance platform 9 corresponding to the height of the upper rail 5, and the hoisting mechanism 10 is detachably arranged on the maintenance platform 9. Specifically, the maintenance platform 9 is a supporting setting of the sintering machine and is used to repair the sintering machine; in this application, by setting the maintenance platform 9 to a height corresponding to the upper rail 5 and completing the construction of the maintenance platform 9 before the installation of the trolley 11, it is convenient to install 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.

[0037] In a specific embodiment, a maintenance platform 9 is provided in front of the sintering machine head, with the heights corresponding to those of the upper rail 5 and the lower rail 6 respectively.

[0038] Furthermore, the traction rope 101 extends in the horizontal direction and is higher than the head star wheel 3 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.

[0039] Furthermore, a hook is provided at the free end of the traction rope 101, which 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 quick connection of multiple trolley groups in sequence and improving the installation efficiency of the trolley 11.

[0040] The installation method of the installation device proposed in this application, using the above-mentioned sintering machine trolley 11 reverse installation device, specifically includes the following steps:

[0041] S1, such as Figure 1 As shown, the head drive device 4, 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 sintering machine are assembled to ensure that the head drive device 4, head star wheel 3 and 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.

[0042] In a specific embodiment, components such as the feeding system, ignition system, wind box and sealing cover of the sintering machine are also installed simultaneously.

[0044] Specifically, several trolleys 11 form a trolley group, and the trolleys 11 in the same group are closely attached to each other; the trolley group can be arranged on the upper track 5 or part of the trolley group is arranged on the upper track 5, and as the trolleys 11 are installed one by one, the trolleys 11 on the upper track 5 are gradually reduced, the new trolleys 11 are hoisted to the upper track 5 one by one by the crane mechanism 12, and the new trolleys 11 are continuously supplemented to form the trolley group, so that continuous operation can be carried out.

[0046] Specifically, the hoisting mechanism 10 is installed on the center extension line of the sintering machine, 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 track 2.

[0047] In a specific embodiment, the trolley group includes five trolleys 11, and the traction rope 101 is connected to the fifth trolley 11 of the trolley group each time.

[0048] S4, as shown in the figure, starting the hoisting mechanism 10, and moving the trolley group closest to the head curved track 2 to the direction of the head curved track 2 through the traction rope 101; preferably, the moving speed of the trolley group is not too fast, so as to accurately control the installation of the trolleys 11. Figure 3

[0049] S5, when the first trolley 11 of the trolley group closest to the head curved track 2 enters the head curved track 2, stopping the operation of the hoisting mechanism 10, and making the clamping wheel of the first trolley 11 engage with the head star wheel 3; specifically, when each clamping ring on the front side of the first trolley 11 enters a tooth groove on the tooth plate on the two sides of the head star wheel 3, the operation of the hoisting mechanism 10 is stopped, and at this time, the other trolleys 11 of the trolley group are located on the upper track 5.

[0050] S6, operating the head driving device 4 to make the head star wheel 3 rotate reversely, and drive the first trolley 11 to move along the head curved track 2 by a set distance, and then stopping the operation of the head star wheel 3.

[0051] Specifically, the set distance can be set according to the needs, which can be set to stop the operation of the head driving device 4 when the first trolley 11 leaves the initial position of entering the head curved track 2, so that the head curved track 2 has space to accommodate another trolley 11; or stopping the operation of the head driving device 4 when the first trolley 11 leaves the head curved track 2 and enters the lower track 6, so as to ensure that the head curved track 2 has enough space to accommodate another trolley 11. ​

[0052] 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.

[0053] Specifically, after untying the traction rope 101, the hoisting mechanism 10 is reversed to allow the traction rope 101 to be reeled in 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, as 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 .

[0054] S8, such as Figure 5 As shown, the traction rope 101 is connected to the next vehicle group, and the hoisting mechanism 10 and the head drive device 4 are operated alternately until the trolley 11 covers the lower track 6.

[0055] 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 under the drive of 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 thus all the trolleys 11 of the previous group 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. The adjacent trolleys 11 are in close contact and move toward 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.

[0056] S9, such as Figure 6 As shown, after the trolleys 11 are fully installed on the lower rail 6, the hoisting mechanism 10 and the head drive 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 point, the head curved rail 2, the lower rail 6, and the tail curved rail 8 are all fully installed with trolleys 11, and the trolleys 11 are all in close contact with each other; however, the upper rail 5 is not yet fully installed with trolleys 11.

[0057] Specifically, the hoisting mechanism 10 and the head driving device 4 are repeatedly operated alternately 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.

[0058] S10, such as Figure 7As shown, the trolleys 11 are installed one by one on the upper rail 5 through the driving mechanism 12, filling 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 covered with trolleys 11, and the installation of all trolleys 11 is completed.
