Description

Technical Field

[0001] The present invention relates to the technical field of supporting mechanism installation in a cylindrical assembly process, in particular to a supporting mechanism installation device that does not require an elastic rope during the cylindrical assembly process. Background Art

[0002] Before the cylinder is assembled into the barrel, a support mechanism needs to be installed on the surface of the cylinder. Each cylinder has several support mechanisms, and each support mechanism is composed of several pieces. Currently, there are many problems in the installation process of the support mechanism. For example, before installing the support mechanism, the operator needs to install an elastic rope on the cylinder. Due to the heavy weight of the support mechanism, to prevent the elastic rope from being unable to tighten the support mechanism, the elastic rope has little elasticity, and the operator needs to use a lot of force to complete the installation of the elastic rope, which has a high labor intensity. For each support mechanism installed, the first operator needs to pull up the elastic rope, the second operator holds the already installed support mechanism below, and the third operator slowly inserts the support mechanism into the elastic rope and installs it on the cylinder. Each support mechanism requires the cooperation of three people to complete the installation. In addition, due to the limited space for pulling up the elastic rope, the gap between the support mechanism and the cylinder is small during the installation process, making it difficult for personnel to observe the position of the pins and pin holes, which often causes the pins of the support mechanism to scratch the heat-resistant layer on the surface of the cylinder. Summary of the Invention

[0003] In response to the above problems, the present invention aims to provide an auxiliary support mechanism installation device for the cylindrical assembly process, which can limit the automatic falling off of the five support mechanisms under the cylinder due to gravity; and set a foot-operated quick lifting mechanism to reduce the operator's bending movement and reduce the labor load.

[0014] Reference Figures 1 to 4 As shown, the present invention is a device for installing an auxiliary support mechanism during the assembly process of a cylinder. It includes a walking mechanism 1, a pedal-type rapid lifting mechanism 2, a fine-adjustment lifting mechanism 3, a floating mechanism 4, and an arc-shaped push-pull mechanism 5: The walking mechanism 1 is mainly used to assist the support mechanism installation equipment to move to the assembly station and lock it; The pedal-type rapid lifting mechanism 2 is used to assist the support mechanism installation equipment in rapidly raising the support mechanism over a long distance, and to quickly lower the support mechanism after the support mechanism is assembled; The fine-tuning lifting mechanism 3 is used to make slight adjustments in the height direction of the auxiliary support mechanism installation equipment to adapt to the center height deviation of the parking brackets of different batches of cylinders, and to ensure that there is no gap between the support mechanism and the cylinder after the auxiliary support mechanism installation equipment supports the support mechanism; The floating mechanism 4 is used to achieve slight adjustment of the lateral movement and rotation direction of the arc-shaped push-pull mechanism 5 to adapt to the parking position deviation of the auxiliary support mechanism installation equipment; The arc-shaped push-pull mechanism 5 is used to prevent the five supporting mechanisms below the cylinder from automatically falling off due to gravity; The pedal-type rapid lifting mechanism 2 is composed of a frame 201, a pedal raising plate 202, a limit plate 203, a pedal lowering plate 204, a first connecting rod 205, a second connecting rod 206, a lifting top plate 207, a fixed pulley 208, and a nylon rope 209. The operator steps down on the foot-lifting plate 202, driving the second connecting rod 206 to rotate along the first connecting rod 205 until the second connecting rod 206 and the foot-lifting plate 202 form a straight line at the dead point, and the lifting top plate 207 rises to the highest position and is fixed; the operator steps down on the foot-lowering plate 204, and the nylon rope passes through the fixed pulley to drive the second connecting rod 206 to rotate along the first connecting rod 205, thereby driving the foot-lifting plate 202 to rotate until the foot-lifting plate 202 hits the limit plate 203, and the lifting top plate 207 descends to the lowest position and is fixed; by stepping on the foot-lifting plate 202 and the foot-lowering plate 204, the lifting top plate 207 can be quickly raised / lowered over a long stroke, reducing the operator's bending movements and reducing the workload; The fine-tuning lifting mechanism 3 is composed of a handwheel 301, a screw elevator 302, a guide assembly 303, and a fine-tuning lifting top plate 304. The handwheel 301 drives the screw elevator 302 to rise / fall short distances to adapt to the center height deviation of the parking brackets of different batches of cylinders, ensuring that there is no gap between the support mechanism and the cylinder after the auxiliary support mechanism is installed. The four sets of guide assemblies 303 are used to provide guidance for the rising / falling movement of the screw elevator 302 to prevent the screw elevator 302 from getting stuck due to uneven force. The floating mechanism 4 is composed of a universal ball 401 and a limiting shaft 402, and the universal ball 401 and the limiting shaft 402 are fixed on the fine-tuning lifting top plate 304; The arc push-pull mechanism 5 is composed of a base 501, a first arc support 502, a cam follower 503, a spring latch 504, a second arc support 505, and a third arc support 506. The base 501 is located above the six sets of universal balls 401. The base 501 can be adjusted in the lateral and rotational directions along the limit axis 402 to adapt to the parking position deviation of the auxiliary support mechanism installation equipment to ensure that the arc push-pull mechanism 5 is coaxial with the cylinder; the first arc support 502 is one group, the second arc support 505 is two groups, and the third arc support 506 is two groups. The first arc support 501 is located above the six sets of universal balls 401. The base 501 can be adjusted in the lateral and rotational directions along the limit axis 402 to adapt to the parking position deviation of the auxiliary support mechanism installation equipment to ensure that the arc push-pull mechanism 5 is coaxial with the cylinder; the first arc support 502 is one group, the second arc support 505 is two groups, and the third arc support 506 is two groups. 02 and the second arc support are both provided with a plurality of cam followers 503. The second arc support 505 can perform arc motion along the first arc support 502 and the cam follower 503, and the third arc support 506 can perform arc motion along the second arc support 505 and the cam follower 503, so as to support the supporting mechanism at the corresponding position. There are four groups of spring latches 504, two groups of which are fixed on the first arc support 502 and are used for automatically limiting the position of the second arc support 505 after it is extended into place, and two groups of which are fixed on the second arc support 505 and are used for automatically limiting the position of the third arc support 506 after it is extended into place. The auxiliary support mechanism installation equipment operation method comprises the following steps: 1) After the cylinder is assembled, it is parked on the parking bracket. The first operator moves the auxiliary support mechanism installation equipment to the bottom of the support mechanism installation position and locks the travel mechanism 1; 2) The second operator installs the lowest support mechanism onto the cylinder. During installation, pay special attention to the vertical insertion of the support mechanism pin into the cylinder pin hole and the pin cannot come into contact with the heat shield on the cylinder surface. 3) The first operator steps on the foot-operated lifting plate 202, and the auxiliary support mechanism installation device rises into place. The first operator checks whether there is a gap between the first arc support 502 and the support mechanism. If there is a gap, the first operator manually adjusts the lifting mechanism 3 to make the first arc support 502 fit the support mechanism. The installation of the lowermost support mechanism is completed; 4) The first and second operators simultaneously install the lower left and right two-petal support mechanisms and manually pull the second arc support 505 to support the lower left and right two-petal support mechanisms. After the second arc support 505 is stretched into place, the spring latch 504 fixed to the first arc support 502 automatically extends to fix the second arc support 505; 5) The first and second operators simultaneously install the left and right two-petal support mechanisms and manually pull the third arc support 506 to support the left and right two-petal support mechanisms. After the third arc support 506 is stretched into place, the spring latch 504 fixed to the second arc support 505 automatically extends to fix the third arc support 506; 6) The operator completes the installation of the three upper support mechanisms in sequence. The three upper support mechanisms will not fall off due to gravity, so there is no need to install the equipment with auxiliary support mechanisms; 7) The operator installs the straps on the support structure to prevent the five support structures at the bottom from falling off automatically due to gravity during the hoisting process of the cylinder; 8) The first operator steps on the descending pedal 204, and the auxiliary support mechanism installation equipment descends into place. The first operator and the second operator simultaneously pull the spring latch 504, causing the third arc support 506 and the second arc support 505 to automatically retract; 9) The first operator unlocks the traveling mechanism 1 and moves the auxiliary support mechanism installation equipment to the next assembly station, completing the installation of each support mechanism in sequence; The present invention has many specific application paths. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be considered as the scope of protection of the present invention.
