The efficiency is increased by 200% compared with the original elastic rope fixing, and the support mechanism pins are prevented from scratching the heat protection layer on the surface of the cylinder due to the small installation space.

Description

Technical Field

[0001] This utility model relates to the field of support mechanism installation technology in the process of cylindrical assembly, and in particular to a support mechanism installation device that does not require elastic ropes in the process of cylindrical assembly. Background Technology

[0002] Before the cylinder is assembled into the cylindrical body, a support mechanism needs to be installed on the cylinder's surface. Each cylinder has several support mechanisms, and each support mechanism consists of several blocks. 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 elastic ropes on the cylinder. Due to the large weight of the support mechanism, the elastic ropes have low elasticity, and the operator needs to exert a lot of force to install them to prevent them from failing to secure the support mechanism. This results in high labor intensity for the operator. For each support mechanism, the first operator needs to pull the elastic rope forcefully, the second operator needs to hold the already installed support mechanism below, and the third operator needs to slowly thread the support mechanism through the elastic rope and install it onto the cylinder. Each support mechanism requires three people to cooperate to complete the installation. Furthermore, 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. This often results in the support mechanism pins scratching the heat-insulating layer on the cylinder's surface. Utility Model Content

[0003] To address the above-mentioned problems, this application aims to provide an auxiliary support mechanism installation device for the assembly of cylinders, which can prevent the five support mechanisms at the bottom of the cylinder from automatically falling off due to gravity; and a foot-operated rapid lifting mechanism is provided to reduce the bending movements of operators and reduce labor load.

[0004] This application provides the following technical solutions to achieve the above effects:

[0005] An auxiliary support mechanism installation device for use in the assembly process of a cylinder, the auxiliary support mechanism installation device comprising a rapid lifting mechanism, a fine-tuning lifting mechanism, a floating mechanism, and an arc-shaped push-pull mechanism, wherein:

[0006] The rapid lifting mechanism is used to assist the support mechanism in quickly raising the support mechanism over a long distance and quickly lowering it after the support mechanism is assembled. A fine-tuning lifting mechanism is installed on the rapid lifting mechanism. The fine-tuning lifting mechanism is used to make small adjustments to the height of the support mechanism in order to adapt to the center height deviation of the cylindrical parking support of different batches, and to ensure that there is no gap between the support mechanism and the cylinder after the support mechanism is installed.

[0007] A floating mechanism is installed on the fine-tuning lifting mechanism, and an arc-shaped push-pull mechanism is located above the floating mechanism. The floating mechanism is used to make minor adjustments to the lateral and rotational directions of the arc-shaped push-pull mechanism to accommodate deviations in the parking position of the auxiliary support mechanism. The arc-shaped push-pull mechanism is used to prevent the lower block support mechanism of the cylinder from automatically falling off due to gravity.

[0008] Furthermore, the foot-operated rapid lifting mechanism includes a frame, a foot-operated raising plate, a limiting plate, a foot-operated lowering plate, a first connecting rod, a second connecting rod, a lifting top plate, a fixed pulley, and a nylon rope;

[0009] Both the foot pedal riser plate and the foot pedal lowering plate are connected to one end of the first connecting rod at the same end. A limiting plate is provided on the frame next to the foot pedal riser plate.

[0010] The second link is connected to the middle of the first link. The second link can rotate along the first link until the second link and the foot pedal rise plate form a straight line and are at the dead point position, at which point the lifting top plate rises to the highest position and is fixed.

[0011] The fixed pulley is fixed to the bottom of the frame. The nylon rope passes through the fixed pulley, with one end connected to the second connecting rod and the other end connected to the foot pedal lowering plate. The nylon rope drives the second connecting rod to rotate along the first connecting rod, thereby driving the foot pedal raising plate to rotate until the foot pedal raising plate touches the limit plate, and the lifting top plate descends to the lowest position and is fixed.

[0012] Furthermore, the fine-tuning lifting mechanism includes a handwheel, a screw jack, a guide assembly, and a fine-tuning lifting top plate; wherein,

[0013] The handwheel drives the screw jack to rise or fall a short distance via a coupling.

[0014] The guide assembly is installed on the lower surface of the fine-adjustment lifting top plate, on the same side as the screw jack, and is used to guide the upward / downward movement of the screw jack.

[0015] Furthermore, the floating mechanism is disposed on the fine-tuning lifting top plate, and includes a universal ball and a limiting shaft. The universal ball is fixed on the upper surface of the fine-tuning lifting top plate, and one end of the limiting shaft is fixed to the fine-tuning lifting top plate, while the other end protrudes from the fine-tuning lifting top plate.

[0016] Furthermore, the arc-shaped push-pull mechanism includes a base, on which are a plurality of arc supports, and a cam follower is provided in the arc support; a second arc support is provided inside the arc surface of the first arc support, and a third arc support is provided inside the arc surface of the second arc support; spring pins are provided at the edges of the first arc support and the second arc support.

[0017] The base is located above the six sets of universal balls, and the protruding end of the limiting shaft is located inside the base. The base can be adjusted to move laterally and rotate along the limiting shaft to accommodate the deviation of the auxiliary support mechanism's installation equipment parking position and ensure that the arc-shaped push-pull mechanism is coaxial with the cylinder.

[0018] Furthermore, the arc-shaped push-pull mechanism includes a first arc support, two second arc supports, and two third arc supports. Both the first and second arc supports are equipped with several cam followers. The second arc supports move in an arc along the first arc support and the cam followers, and the third arc supports move in an arc along the second arc support and the cam followers, thus supporting the support mechanism at the corresponding position. The arc-shaped push-pull mechanism includes four sets of spring pins. Two sets of spring pins are fixed to the first arc support for automatic limiting after the second arc support extends to its full position, and two sets of spring pins are fixed to the second arc support for automatic limiting after the third arc support extends to its full position.

[0019] Compared with the prior art, the advantages of this application are as follows:

[0020] This application proposes a support mechanism installation device for cylindrical assembly that eliminates the need for elastic ropes. It prevents the five support mechanisms at the bottom of the cylinder from automatically detaching due to gravity; it incorporates a foot-operated rapid lifting mechanism, reducing operator bending and workload; it replaces the traditional elastic rope fixing method, reducing the number of operators from three to one person per support mechanism; its efficiency is increased by 200% compared to the original elastic rope fixing method, and it avoids the support mechanism pins scratching the cylinder's surface heat-resistant layer due to limited installation space.

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] Reference Figures 1 to 4 As shown, this utility model discloses an auxiliary support mechanism installation device for the assembly of cylinders. It includes a walking mechanism 1, a foot-operated rapid lifting mechanism 2, a fine-tuning lifting mechanism 3, a floating mechanism 4, and an arc-shaped push-pull mechanism 5.

[0032] The walking mechanism 1 is mainly used to assist the support mechanism in moving the installation equipment to the assembly station and locking it in place;

[0033] The foot-operated rapid lifting mechanism 2 is used to assist the support mechanism in rapidly raising the support mechanism over a long distance for the installation equipment, and to quickly lower it after the support mechanism is assembled.

[0034] The fine-tuning lifting mechanism 3 is used to make minor adjustments to the height of the auxiliary support mechanism in the direction of the equipment installation, so as to adapt to the center height deviation of the cylindrical parking support of different batches, and to ensure that there is no gap between the auxiliary support mechanism and the cylinder after the equipment installation is supported by the support mechanism.

[0035] The floating mechanism 4 is used to make minor adjustments to the lateral and rotational directions of the arc-shaped push-pull mechanism 5 to accommodate deviations in the parking position of the equipment installed on the auxiliary support mechanism.

[0036] 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;

[0037] The foot-operated rapid lifting mechanism 2 consists of a frame 201, a foot-operated lifting plate 202, a limiting plate 203, a foot-operated 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. When the operator steps down on the foot pedal raising plate 202, it causes the second connecting rod 206 to rotate along the first connecting rod 205 until the second connecting rod 206 and the foot pedal raising plate 202 form a straight line and reach a dead point, at which point the lifting ceiling 207 rises to its highest position and is fixed. When the operator steps down on the foot pedal lowering plate 204, the nylon rope passes through the fixed pulley and causes the second connecting rod 206 to rotate along the first connecting rod 205, thereby causing the foot pedal raising plate 202 to rotate until it touches the limit plate 203, at which point the lifting ceiling 207 descends to its lowest position and is fixed. By stepping on the foot pedal raising plate 202 and the foot pedal lowering plate 204, the lifting ceiling 207 can be raised / lowered quickly over a long stroke, reducing the operator's bending movements and reducing labor load.

[0038] The fine-tuning lifting mechanism 3 consists of a handwheel 301, a screw jack 302, a guide assembly 303, and a fine-tuning lifting top plate 304. The handwheel 301 drives the screw jack 302 to rise / fall short distances to accommodate the center height deviation of different batches of cylindrical parking supports, 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 guide the rising / falling movement of the screw jack 302 and prevent the screw jack 302 from jamming due to uneven force.

[0039] The floating mechanism 4 consists 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-adjustment lifting top plate 304.

[0040] The arc-shaped push-pull mechanism 5 consists of a base 501, a first arc support 502, a cam follower 503, a spring pin 504, a second arc support 505, and a third arc support 506. The base 501 is located above six sets of universal balls 401. The base 501 can be adjusted laterally and in rotational direction along the limiting shaft 402 to accommodate deviations in the parking position of the auxiliary support mechanism and ensure that the arc-shaped push-pull mechanism 5 is coaxial with the cylinder. There is one set of first arc supports 502, two sets of second arc supports 505, and two sets of third arc supports 506. Both the first arc support 502 and the second arc support 505 are equipped with several cam followers 503. The second arc support 505 can move in an arc along the first arc support 502 and the cam followers 503. The third arc support 506 can move in an arc along the second arc support 505 and the cam followers 503, which are used to support the support mechanism at the corresponding position. There are four sets of spring pins 504. Two sets are fixed on the first arc support 502 for automatic limiting after the second arc support 505 is extended to the position. Two sets are fixed on the second arc support 505 for automatic limiting after the third arc support 506 is extended to the position.

[0041] The method for installing and operating the auxiliary support mechanism includes the following steps:

[0042] 1) After the cylinder is fully assembled, it is placed on the parking support. The first operator moves the auxiliary support mechanism installation equipment to the position below the support mechanism installation position and locks the traveling mechanism 1.

[0043] 2) The second operator installs the bottom support mechanism onto the cylinder. During installation, special attention should be paid to inserting the support mechanism pin vertically into the pin hole of the cylinder, and the pin should not contact the heat-insulating layer on the surface of the cylinder.

[0044] 3) The first operator steps on the foot pedal lifting plate 202, and the auxiliary support mechanism installation equipment rises into place. The first operator observes whether there is a gap between the first arc support 502 and the support mechanism. If there is a gap, the operator manually cranks the lifting mechanism 3 to make the first arc support 502 fit with the support mechanism. The installation of the bottom support mechanism is then complete.

[0045] 4) The first operator and the second operator simultaneously install the lower left and lower right two-lobed support mechanisms, and manually pull the second arc support 505 to support the lower left and lower right two-lobed support mechanisms. After the second arc support 505 is stretched into place, the spring pin 504 fixed on the first arc support 502 automatically extends to fix the second arc support 505.

[0046] 5) The first operator and the second operator 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 pin 504 fixed on the second arc support 505 automatically extends to fix the third arc support 506.

[0047] 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 no auxiliary support mechanism is needed to install the equipment.

[0048] 7) The operator installs the hoops onto the support mechanism to prevent the five lower support mechanisms from falling off automatically due to gravity during the lifting of the cylinder;

[0049] 8) The first operator steps on the foot pedal lowering plate 204, and the auxiliary support mechanism installation equipment is lowered into place. The first operator and the second operator simultaneously pull the spring pin 504, so that the third arc support 506 and the second arc support 505 automatically retract.

[0050] 9) The first operator unlocks the walking mechanism 1 and moves the auxiliary support mechanism installation equipment to the next assembly station, and completes the installation of each support mechanism in sequence;

[0051] There are many specific applications of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this utility model, and these improvements should also be considered within the protection scope of this utility model.
