Description
Technical Field
[0001] The utility model relates to the technical field of shaft sinking supports, in particular to an anti-overturning device for hoisting a shaft sinking derrick. Background Art
[0002] The process shaft derrick is a piece of equipment serving the construction of the process shaft. It usually includes the derrick body, as well as components such as the crown block platform, crown block beam, crown block, slag discharge platform, crown block platform enclosure, lightning rod, etc. arranged on the derrick. Among them, when installing the derrick, the method of "assembling in pieces and hoisting as a whole" is usually adopted, that is, the derrick is assembled in advance, and then one or more of the remaining components are assembled onto the derrick. When using a crane or other hoisting device to hoist the derrick to the derrick foundation for installation, after hoisting the derrick to the designated position, it is necessary to place the erected derrick stably above the derrick foundation, use the prepared I-beams and iron plates to pad each derrick anchor foot, weld and fix the I-beams and iron plates to the derrick anchor foot support plate, and finally install and fix the anchor bolts embedded in the foundation into the reserved holes in the foundation, wedge and expand tightly with the mating surface of the bearing platform, loosen the hook of the crane, and at the same time use wire ropes and manual hoists to tighten the guy ropes at the four corners of the derrick to ensure the stability of the derrick, and then remove the wire ropes of the crane and carry out secondary grouting of the derrick foundation anchor bolts. The secondary grouting uses C30 fine aggregate concrete for formwork pouring and is vibrated and compacted with a vibrating pump.
[0003] In the prior art, when stabilizing the hoisted derrick, it is necessary to use the method of secondary grouting and vibrating and compacting with a vibrating pump to ensure the subsequent stability of the derrick and prevent it from overturning. At the same time, before completing the secondary fixation, it is necessary to use wire ropes to assist in fixing the derrick. However, due to the large mass and volume of the derrick, before completing the secondary grouting and vibrating and compacting, if the derrick is affected by wind, especially when the wind is strong, due to the use of wire ropes for auxiliary tensioning and fixing, the wire ropes may shake and other situations may occur, which makes the fixation of the derrick relatively unstable and ultimately leads to the overturning of the derrick. Therefore, in order to avoid the overturning of the derrick, construction workers may stop the work of hoisting the derrick and wait until the wind stops before re-hoisting, which consumes resources and delays the construction time.
[0004] Therefore, there is an urgent need for an anti-overturning device for hoisting a shaft sinking derrick to solve the above problems, so that after the derrick is hoisted to the designated position for installation, its position is relatively stable, and then the hoisting of the remaining components can be carried out.

[0040] Embodiment 1
[0041] It should be understood that when stabilizing the derrick 100 after hoisting, the method of secondary grouting and vibrating pump ramming should be used to ensure the stability of the subsequent derrick 100 and prevent it from overturning. At the same time, before completing the secondary fixation, steel wires should be used to assist in fixing the derrick 100. However, due to the large mass and volume of the derrick 100, before completing the secondary grouting and vibrating pump ramming, if the derrick 100 is affected by wind, especially when the wind force is large, due to the use of steel wires for auxiliary tensioning and fixing, the steel wires may shake, etc., which may make the fixation of the derrick 100 relatively unstable and ultimately lead to the overturning of the derrick 100. Therefore, in order to avoid the overturning of the derrick 100, the construction personnel may stop the hoisting work of the derrick 100 and resume hoisting after the wind stops, which will consume resources and delay the construction time.
[0042] Therefore, in order to improve the above problems, this embodiment provides an anti-overturning device for hoisting a sinking shaft derrick 100, which mainly includes a bearing platform 300 and four first support arms 400. This device is mainly used to support the derrick 100 after hoisting to keep it stable, so as to hoist subsequent components.
[0043] Among them, as Figure 1 shown, the bearing platform 300 is arranged between multiple bases 200, and the surface of the bearing platform 300 is lower than the surface of the bases 200, so as to avoid collision between the derrick 100 and the derrick 100 when the derrick 100 is hoisted and turned. At the same time, it is also convenient for the installation and transfer of the bearing platform 300.
[0044] In this embodiment, as Figure 1 and Figure 3 shown, four first support arms 400 are arranged on the upper surface of the bearing platform 300. One ends of the four first support arms 400 are respectively arranged at the four corners of the bearing platform 300, and the other ends of the four first support arms 400 are detachably connected to the frames at the four corners of the derrick 100. Specifically, one end of the first support arm 400 and the derrick 100 can be connected by means of snap connection, threaded connection, etc., so that the four first support arms 400 support the derrick 100 at the same time, and then cooperate with the steel wires to assist in fixing the derrick 100, making the position of the derrick 100 stable, so as to avoid the derrick 100 from overturning.
[0045] In this embodiment, the derrick 100 is supported by four first support arms 400, and then the wire rope is used to assist in the auxiliary support and fixation of the derrick 100, so that the position of the derrick 100 is further stabilized, and the derrick 100 is prevented from tipping over in the case of strong wind.
[0046] In a more complete solution, as Figures 1 - 3 shown, four first receiving grooves 310 are provided on the surface of the bearing platform 300. Specifically, the four first receiving grooves 310 are respectively arranged at the four corners of the bearing platform 300, and the four first receiving grooves 310 are respectively opened in the direction from the four corners of the bearing platform 300 towards the center of the bearing platform 300. Among them, the four first receiving grooves 310 are respectively adapted to the four first support arms 400, and one end of the first support arm 400 is rotatably arranged at one end of the first receiving groove 310 facing the center of the bearing platform 300, and the other end of the first support arm 400 can rotate relative to the first receiving groove 310 around one end of the first support arm 400, so that the first support arm 400 can be received in the first receiving groove 310, and when the derrick 100 needs to be supported, one end of the first support arm 400 can rotate relative to the first receiving groove 310 to the frame of the derrick 100 and abut against the frame of the derrick 100. Therefore, when the device is not in use, the occupied space is small, which is convenient for the transfer and installation of the device.
[0047] Among them, the first support arm 400 can adopt structures such as hydraulic cylinders, electric cylinders or telescopic rods, so that the length of the first support arm 400 can be controlled, and then the connection point between the first support arm 400 and the derrick 100 can be controlled, so that the first support arm 400 supports the derrick 100 from different points, making the support of the first support arm 400 on the derrick 100 stable, and making the device applicable to derricks 100 of different heights.
[0048] Among them, as Figures 1 - 3 shown, a first hydraulic cylinder 340 is provided at one end of the first receiving groove 310 away from the center of the bearing platform 300. One end of the first hydraulic cylinder 340 is rotatably connected to the arm body of the first support arm 400, so that the first hydraulic cylinder 340 pushes the first support arm 400 to rotate relative to the first receiving groove 310. Specifically, when the first hydraulic cylinder 340 extends, one end of the first hydraulic cylinder 340 abuts against the first support arm 400, thereby pushing the first support arm 400 to rotate. At the same time, the end of the first hydraulic cylinder 340 connected to the first support arm 400 rotates, so that the included angle between the first hydraulic cylinder 340 and the first support arm 400 changes, so that the first hydraulic cylinder 340 is continuously connected to the first support arm 400, and then the first hydraulic cylinder 340 supports the first support arm 400, so that the position of the first support arm 400 is stable, and then the support of the first support arm 400 on the derrick 100 is stable.
[0049] Wherein, when the first support arm 400 is received in the first receiving groove 310, there is an included angle between the first hydraulic cylinder 340 and the first support arm 400. The initial angle size of the included angle between the first hydraulic cylinder 340 and the first support arm 400 can be determined according to the length of the first support arm 400 and the height when the other end of the first support arm 400 rises to the highest point, so that while the first hydraulic cylinder 340 pushes the first support arm 400 to rotate, the support of the first hydraulic cylinder 340 to the first support arm 400 is relatively stable.
[0050] In this embodiment, as Figure 1 and Figure 5 shown, a ball hinge end 700 is provided at the other end of the first support arm 400, and a detachable rubber pad 710 is provided on the surface of the ball hinge end 700. Specifically, the surface of the ball hinge end 700 in contact with the derrick 100 adopts a planar structure, so that when the first support arm 400 abuts against the derrick 100, the plane of the ball hinge end 700 abuts against and fits the frame of the derrick 100. And due to the setting of the ball hinge end 700, when the first support arm 400 supports the derrick 100, the ball hinge end 700 can adapt to the angle changes of each connecting steel in the frame of the derrick 100, so that the connection between the other end of the first support arm 400 and the derrick 100 is relatively stable, and further the support of the first support arm 400 to the derrick 100 is relatively stable.
[0051] Wherein, as Figure 1 and Figure 5 shown, a detachable rubber pad 710 is provided on the plane of the ball hinge end 700, so as to increase the friction between the ball hinge end 700 and the derrick 100, make the connection between the first support arm 400 and the derrick 100 stable, and at the same time, avoid the mutual wear between the first support arm 400 with high rigidity and large hardness and the derrick 100.
[0052] In some embodiments, as Figures 1 - 3 shown, the device further includes a plurality of second support arms 500 and a plurality of second receiving grooves 320, and the number of the second support arms 500 is the same as that of the second receiving grooves 320, and the second receiving grooves 320 are adapted to the second support arms 500, so as to facilitate the second support arms 500 to be received in the second receiving grooves 320.
[0053] Among them, the second storage groove 320 is opened along the side of the bearing platform 300 towards the center of the bearing platform 300. One end of the second support arm 500 is rotatably arranged at one end of the second storage groove 320 towards the center of the bearing platform 300, and the other end of the second support arm 500 can rotate relative to the second storage groove 320 around one end of the second support arm 500, so that the second support arm 500 can rotate to the frame of the derrick 100 and be connected to the derrick 100, thereby supporting the derrick 100. Among them, the second support arm 500 and the derrick 100 bracket can adopt detachable connection methods such as snap connection and threaded connection.
[0054] The second storage grooves 320 are respectively and evenly arranged between two adjacent first storage grooves 310. Specifically, the number of the second storage grooves 320 between all two adjacent first storage grooves 310 is the same, and a plurality of second storage grooves 320 arranged between two adjacent first storage grooves 310 are arranged at intervals in sequence.
[0055] Among them, the second support arm 500 can adopt structures such as hydraulic cylinders, electric cylinders or telescopic rods, so that the length of the second support arm 500 can be controlled, and further the connection point between the second support arm 500 and the derrick 100 can be controlled, so that the second support arm 500 supports the derrick 100 from different positions, making the support of the second support arm 500 for the derrick 100 stable, and making the device applicable to derricks 100 of different heights.
[0056] Among them, a second hydraulic cylinder 350 is provided at one end of the second storage groove 320 away from the center of the bearing platform 300. One end of the second hydraulic cylinder 350 is rotatably connected to the arm body of the second support arm 500, so that the second hydraulic cylinder 350 pushes the second support arm 500 to rotate relative to the second storage groove 320. Specifically, when the second hydraulic cylinder 350 extends, one end of the second hydraulic cylinder 350 abuts against the second support arm 500, thereby pushing the second support arm 500 to rotate. At the same time, the end of the second hydraulic cylinder 350 connected to the second support arm 500 rotates, so that the included angle between the second hydraulic cylinder 350 and the second support arm 500 changes, so that the second hydraulic cylinder 350 is continuously connected to the second support arm 500, and further the second hydraulic cylinder 350 supports the second support arm 500, so that the position of the second support arm 500 is stable, and further the support of the second support arm 500 for the derrick 100 is stable.
[0057] In this embodiment, as Figure 1 and Figure 5As shown, the other end of the second support arm 500 is also provided with a ball hinge end 700, and a rubber pad 710 is provided on the surface of the ball hinge end 700. The other end of the first support arm 400 is provided with a ball hinge end 700, and a detachable rubber pad 710 is provided on the surface of the ball hinge end 700. Specifically, the surface of the ball hinge end 700 that abuts against the derrick 100 adopts a planar structure. Thus, when the second support arm 500 abuts against the derrick 100, the plane of the ball hinge end 700 abuts against and fits the frame of the derrick 100. And due to the setting of the ball hinge end 700, when the second support arm 500 supports the derrick 100, it can adapt to the angular changes of each connecting steel in the frame of the derrick 100 through the ball hinge end 700. As a result, the connection between the other end of the second support arm 500 and the derrick 100 is relatively stable, and further the support of the second support arm 500 to the derrick 100 is relatively stable.
[0058] Among them, as Figure 1 and Figure 5 shown, a detachable rubber pad 710 is provided on the plane of the ball hinge end 700, so as to increase the friction between the ball hinge end 700 and the derrick 100, making the connection between the second support arm 500 and the derrick 100 stable. At the same time, it avoids the situation of mutual wear between the rigid and relatively hard second support arm 500 and the derrick 100.
[0059] In this embodiment, when the derrick 100 is installed on the base 200, through the elongation of the four first hydraulic cylinders 340 and multiple second hydraulic cylinders 350, further the four first hydraulic cylinders 340 push the other ends of the four first support arms 400 to rotate to the frame of the derrick 100 and connect with the derrick 100, and multiple second hydraulic cylinders 350 push multiple second support arms 500 to the derrick 100 to connect with the derrick 100. Through the support of the first support arm 400 and the second support arm 500 to the derrick 100, the position of the derrick 100 is made stable, and further the situation of the derrick 100 tipping over is avoided.
[0060] Among them, according to factors such as the mass, height of the derrick 100 and the on-site environment, etc., it is possible to select to drive the four first support arms 400 or multiple second support arms 500, or drive the four first support arms 400 and multiple second support arms 500 simultaneously.
[0061] In some embodiments, as Figure 1 shown, a plurality of lifting columns 330 arranged at intervals in sequence are provided on the lower side of the loading platform 300. Among them, the lifting columns 330 can adopt devices such as hydraulic cylinders, electric push rods or telescopic rods. In this embodiment, the lifting columns 330 adopt hydraulic cylinders, so as to control the height of the loading platform 300 through the lifting columns 330, making the loading platform 300 adapt to derricks 100 of different heights.
[0062] Among them, as Figure 4As shown in the figure, the device further includes a transfer trolley 600. The transfer trolley 600 is provided with a transfer platform 610. The bearing platform 300 is detachably connected to the transfer platform 610. Specifically, when it is necessary to transfer the bearing platform 300, the bearing platform 300 can be lifted to a certain height by the lifting column 330. Then, the transfer trolley 600 is displaced to the lower side of the bearing platform 300, so that the upper surface of the transfer platform 610 is opposite to the lower surface of the bearing platform 300. At this time, the lifting column 330 is lowered, so that the bearing platform 300 descends onto the transfer platform 610. Then, the bearing platform 300 is connected to the rotating platform, thus preventing the bearing platform 300 from falling during transportation. Finally, the bearing platform 300 is transferred by the transfer trolley 600, making the transfer of the bearing platform 300 relatively simple.
[0063] Among them, the transfer platform 610 and the bearing platform 300 can be connected by means of screw connection, clamping or plugging.
