Description

Technical Field

[0001] This utility model relates to the field of tire crane technology, specifically a tire crane outrigger fixing device. Background Technology

[0002] Tire-mounted cranes are widely used in construction, industry and other fields. During operation, the outrigger fixing device is crucial to ensuring the stability of the crane.

[0003] Tire cranes are used not only on concrete surfaces but also frequently on soft ground. Since the ground may be relatively soft, the outriggers may not provide sufficient support and may sink into the ground during operation. This makes the tire crane less adaptable and practical, as it cannot cope with the problem of the outriggers sinking easily in soft ground.

[0004] Furthermore, when tire cranes are working on land, the traditional and mainstream method is to install reinforcing bars at the outrigger fixing devices and insert them into the ground to improve the stability of the outrigger fixing devices. However, the reinforcing bars are inserted into the ground by external force, and they may become skewed during the insertion process. This means that the reinforcing bars do not provide a good reinforcement and stability effect. Moreover, it takes a lot of effort to pull out the reinforcing bars manually, resulting in high labor intensity for personnel. Utility Model Content

[0005] To address the above problems, this utility model provides a tire crane outrigger fixing device, which solves the aforementioned issues.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tire crane outrigger fixing device, comprising a tire crane, wherein the lower part of the tire crane is provided with an outrigger mechanism, the outrigger mechanism comprising a support leg, and one end of the support leg being connected to a hydraulic cylinder;

[0007] One end of the hydraulic cylinder is provided with a cylinder rod, one end of the cylinder rod is connected to a connector, a connecting cylinder is installed on the outside of the connector, and a support leg seat is connected to the bottom of the connecting cylinder;

[0008] The support leg base has several fixing pins threaded to one side, and an extension seat is rotatably connected to one end of each fixing pin. A support block is connected to the bottom of the support leg base, and several auxiliary blocks are connected to the bottom of the support leg base.

[0009] Preferably, two support platforms are connected to each side of the support leg, and a fixing rod is connected between the two support platforms.

[0010] Preferably, a positioning sleeve is connected between the two supports, a reinforcing rod is provided in the positioning sleeve, and a pressure plate is connected to the top of the reinforcing rod.

[0011] Preferably, the reinforcing rod has several through holes, and the outside of the positioning sleeve has an insertion hole, into which a positioning pin is inserted, and the positioning pin passes through the through holes.

[0012] Preferably, a positioning hole is provided on one side of the support leg base, and an installation hole is provided on the side of the support leg base, wherein the installation hole communicates with the positioning hole.

[0013] Preferably, a connecting pin is connected in the mounting hole, and the connecting pin passes through the through hole on the reinforcing rod.

[0014] Preferably, the support leg is connected to the tire crane, and the bottom of the support leg is connected to several casters.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When working on land, this application can increase the contact area between the outriggers and the ground through the extension seat, which can distribute the pressure and prevent the outriggers from sinking into the ground. This solves the problem that when the tire crane is working on land, the contact area between the outriggers and the ground is relatively small, which not only causes greater pressure but also makes it easy to sink into the ground. This is beneficial to improving the adaptability and practicality of the tire crane.

[0017] 2. This application, through the use of a positioning sleeve and connecting pin in conjunction with a reinforcing rod, ensures that the reinforcing rod remains vertically embedded in the ground during the operation of the tire crane, and can also be pulled out using the force of a hydraulic cylinder. This solves the problem that when most tire cranes are used with reinforcing rods inserted into the ground, the reinforcing rod will be inserted crookedly, and it is difficult to pull it out manually. This ensures that the reinforcing rod is inserted vertically into the ground, reducing the labor intensity of personnel when pulling out the reinforcing rod. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Please see Figures 1 to 7 A tire crane outrigger fixing device includes a tire crane 1. The tire crane 1 has an outrigger mechanism 2 at its lower part. After the tire crane 1 reaches a suitable position, the outrigger fixing device is unfolded and then supported and fixed by the outrigger mechanism 2 to ensure stability during subsequent work. The tire crane 1 and the above-mentioned working process are known technologies and are conventional means that can be understood and implemented by those skilled in the art based on common sense. Those skilled in the art can and should be clear about its specific functions and structure, so they will not be described in detail here. The outrigger mechanism 2 includes a support leg 3, and one end of the support leg 3 is connected to a hydraulic cylinder 4.

[0028] One end of the hydraulic cylinder 4 is provided with a cylinder rod 5. The hydraulic cylinder 4 drives the cylinder rod 5 to rise and fall, so that the cylinder rod 5 drives the connecting cylinder 7 and the outrigger seat 8 to rise and fall through the connector 6. Specifically, the hydraulic cylinder 4 pushes the cylinder rod 5 to fall, so that the cylinder rod 5 drives the outrigger seat 8 to fall and contact the ground, thereby performing the support and fixation work.

[0029] It should be noted that the extension seat 12 needs to be manually unscrewed in advance to extend the outrigger seat 8. Of course, depending on the needs, if the items being hoisted are relatively light, it is not necessary to unscrew the extension seat 12. In this case, the support and fixation work can still be carried out normally. One end of the cylinder rod 5 is connected to the connector 6, and the outside of the connector 6 is equipped with a connecting cylinder 7. The connecting cylinder 7 and the connector 6 are connected by a ball joint. Because in actual operation, it is often difficult to ensure that the contact surface between the outrigger seat 8 and the ground is absolutely horizontal, the ball joint connection allows the outrigger seat 8 to rotate freely relative to the cylinder rod 5 within a certain angle range, just like the universal joint function of the human body. This allows the outrigger seat 8 to automatically adjust its posture to ensure close contact with the ground (rather than rigid tilting), avoid the outrigger seat 8 being partially suspended or subjected to single-point force, thereby maximizing the utilization rate of the support area and improving the stability of the outrigger fixing device. The bottom of the connecting cylinder 7 is connected to the outrigger seat 8.

[0030] Several fixing pins 11 are threadedly connected to one side of the outrigger base 8. The fixing pin 11 is threaded, while the end that mates with the extension base 12 is not threaded. During installation, the operator threaded the fixing pin 11 into the outrigger base 8 and then uses multiple nuts to connect and fix it. Finally, the extension base 12 is connected to one end of the fixing pin 11, and the extension base 12 is rotatably connected to one end of the fixing pin 11. A support block 9 is connected to the bottom of the outrigger base 8, and several auxiliary blocks 10 are connected to the bottom of the outrigger base 8. When using the extension base 12 (while the outrigger base 8 is still suspended), the operator manually rotates the extension base 12, causing it to rotate around the fixing pin 11. At this time, the extension base 12 will unscrew from the bottom of the outrigger base 8, increasing the contact area between the outrigger and the ground, thus dispersing pressure and preventing the outrigger from sinking into the ground.

[0031] It should be further explained that, in order to prevent the bottom of the support leg seat 8 from being suspended too much when the extension seat 12 is spun out, the bottom of the support leg seat 8 is provided with a support block 9 and an auxiliary block 10 to assist the extension seat 12 in providing support, thereby improving the stability of the support leg fixing device when the extension seat 12 is extended and supported.

[0032] It should be further explained that although after the extension seat 12 is extended, there may still be gaps at the bottom of the outrigger seat 8 that may not be in contact with the ground, in actual operation, the hydraulic cylinder 4 pushes the outrigger seat 8 down, which will make the outrigger seat 8 fully in contact with the ground. In other words, the gaps at the bottom of the outrigger seat 8 will be compensated by the softness of the soil. At this time, the extension seat 12 will also make further contact with the soil. Therefore, the increased contact area between the outrigger and the ground will not be affected by the height difference between the extension seat 12 and the outrigger seat 8. This solves the problem that when the tire crane is working on land, the contact area between the outrigger and the ground is relatively small, which not only causes greater pressure but also makes it easy to sink into the soil.

[0033] Two support platforms 13 are connected to each side of the support leg 3, and a fixing rod 14 is connected between the two support platforms 13.

[0034] A positioning sleeve 15 is connected between the two support platforms 13. A reinforcing rod 17 is provided in the positioning sleeve 15. The reinforcing rod 17 is placed directly in the positioning sleeve 15, which can be easily disassembled and installed. When carrying the reinforcing rod 17, the personnel lift the bottom end of the reinforcing rod 17 away from the support leg seat 8. Then, the personnel use the positioning pin 20 to cooperate with the insertion hole 16 on the positioning sleeve 15 and the through hole 19 on the reinforcing rod 17 to position and fix the reinforcing rod 17. The top of the reinforcing rod 17 is connected to a pressure table 18. The function of the pressure table 18 is mainly to facilitate the personnel to embed the reinforcing rod 17 into the ground by tapping.

[0035] The reinforcing rod 17 has several through holes 19. The number and position of the through holes 19, as well as the length of the reinforcing rod 17, can be adjusted by those skilled in the art according to their needs, so that the positioning pin 20 and the connecting pin 23 can properly cooperate with the through holes 19 on the reinforcing rod 17 under different conditions. For the sake of convenience, this application only shows some of the through holes 19, but it should not be limited to what is shown in the accompanying drawings. The degree of disclosure has also met the standard of "that can be achieved by those skilled in the art". The positioning sleeve 15 has an insertion hole 16 on its outside. The positioning pin 20 is inserted into the insertion hole 16 and passes through the through hole 19.

[0036] A positioning hole 21 is provided on one side of the outrigger seat 8, and an installation hole 22 is provided on the side of the outrigger seat 8. The installation hole 22 is connected to the positioning hole 21. When using the reinforcing rod 17, the outrigger seat 8 needs to be pressed down to contact the ground first using the hydraulic cylinder 4, and then the personnel insert the reinforcing rod 17 into the ground.

[0037] Specifically, the reinforcing rod 17 is positioned by the positioning sleeve 15, so the reinforcing rod 17 will remain vertically inserted when embedded in the soil. More specifically, the reinforcing rod 17 will also pass through the positioning hole 21 on the outrigger seat 8 when inserted into the soil. It should be noted that the size of the positioning hole 21 is larger than that of the reinforcing rod 17. This is mainly because the outrigger seat 8 and the hydraulic cylinder rod 5 are connected by a ball joint. Therefore, the outrigger seat 8 is not perfectly horizontal. So the size of the positioning hole 21 needs to be larger than that of the reinforcing rod 17 so that the reinforcing rod 17 can pass through the positioning hole 21 normally.

[0038] A connecting pin 23 is connected in the mounting hole 22. The connecting pin 23 passes through the through hole 19 on the reinforcing rod 17. After the reinforcing rod 17 is inserted into the ground, the reinforcing rod 17 is connected and fixed to the positioning sleeve 15 by the fixing pin 11. At the same time, the connecting pin 23 passes through the through hole 19 on the reinforcing rod 17 and is connected and fixed to the mounting hole 22. At this time, the reinforcing rod 17 is connected and fixed together with the outrigger seat 8.

[0039] It is important to note that regarding the fixing pin 11 on the positioning sleeve 15, it must be emphasized again that whenever the reinforcing rod 17 needs to be moved or adjusted, the fixing pin 11 must be removed first so that the reinforcing rod 17 can move normally in the positioning sleeve 15.

[0040] After the connecting pin 23 connects and fixes the reinforcing rod 17 to the outrigger seat 8, when the tire crane finishes its work and leaves the site, the hydraulic cylinder 4 would normally be needed to lift the outrigger seat 8 to separate it from the ground. However, since the connecting pin 23 connects the reinforcing rod 17 to the outrigger seat 8, the hydraulic cylinder 4 can also lift the reinforcing rod 17 to be pulled out of the ground when it lifts the outrigger seat 8. This eliminates the need for personnel to manually pull out the reinforcing rod 17, which would otherwise require a lot of physical effort.

[0041] After the reinforcing rod 17 is pulled out, the personnel use the connecting pin 23 to separate the reinforcing rod 17 from the outrigger seat 8, and then fix the reinforcing rod 17 back onto the positioning sleeve 15 for carrying.

[0042] The support leg 3 is connected to the tire crane 1. Several casters 24 are connected to the bottom of the support leg 3. The casters 24 are rotatable casters. When the support leg fixing device is deployed, the casters 24 work together to move the support leg mechanism 2 to a suitable position for support and fixing.

[0043] When using this utility model:

[0044] First, after the tire crane 1 reaches the appropriate position, it unfolds the outrigger fixing device. Then, the outrigger mechanism 2 provides support and fixation to ensure stability during subsequent work. The hydraulic cylinder 4 drives the cylinder rod 5 to rise and fall, which in turn drives the connecting cylinder 7 and the outrigger seat 8 to rise and fall through the connector 6. Specifically, the hydraulic cylinder 4 pushes the cylinder rod 5 down, causing the cylinder rod 5 to lower the outrigger seat 8 to contact the ground, thus providing support and fixation. The extension seat 12 needs to be manually unscrewed in advance to extend the outrigger seat 8. Of course, depending on the needs, if the items being hoisted are relatively light, it is not necessary to unscrew the extension seat 12, and the support and fixation work can still be carried out normally.

[0045] Secondly, when using the extension base 12 (while the outrigger base 8 is still suspended), the operator manually rotates the extension base 12, causing it to rotate around the fixing pin 11. At this time, the extension base 12 will rotate out from the bottom of the outrigger base 8, increasing the contact area between the outrigger and the ground, thus dispersing pressure and preventing the outrigger from sinking into the ground. To prevent the bottom of the outrigger base 8 from being suspended too much when the extension base 12 rotates out, a support block 9 and an auxiliary block 10 are provided at the bottom of the outrigger base 8 to assist the extension base 12 in providing support, thereby improving the stability of the outrigger fixing device when the extension base 12 is extended.

[0046] Then, when using the reinforcing rod 17, the outrigger seat 8 needs to be pressed down to contact the ground using the hydraulic cylinder 4 first, and then the reinforcing rod 17 is inserted into the ground. Specifically, the reinforcing rod 17 is positioned by the positioning sleeve 15, so the reinforcing rod 17 will remain vertically inserted when embedded in the ground. More specifically, the reinforcing rod 17 will also pass through the positioning hole 21 on the outrigger seat 8 when inserted into the ground. It should be noted that the size of the positioning hole 21 is larger than that of the reinforcing rod 17, mainly because the outrigger seat 8 and the cylinder rod 5 are connected by a ball joint. Therefore, the outrigger seat 8 is not perfectly horizontal, so the size of the positioning hole 21 needs to be larger than that of the reinforcing rod 17 so that the reinforcing rod 17 can pass through the positioning hole 21 normally.

[0047] Finally, after the reinforcing rod 17 is inserted into the ground, the reinforcing rod 17 is connected and fixed to the positioning sleeve 15 using the fixing pin 11. At the same time, the connecting pin 23 is passed through the through hole 19 on the reinforcing rod 17 and connected and fixed to the mounting hole 22. At this time, the reinforcing rod 17 is connected and fixed together with the outrigger seat 8. After the connecting pin 23 connects and fixes the reinforcing rod 17 to the outrigger seat 8, when the tire crane finishes its work and leaves the site, the hydraulic cylinder 4 would normally need to lift the outrigger seat 8 to separate it from the ground. However, because the connecting pin 23 connects the reinforcing rod 17 to the outrigger seat 8, the hydraulic cylinder 4 can also lift the outrigger seat 8 and pull the reinforcing rod 17 out of the ground at the same time, eliminating the need for personnel to manually pull out the reinforcing rod 17 and expend a lot of physical effort.

[0048] After the reinforcing rod 17 is pulled out, the personnel use the connecting pin 23 to separate the reinforcing rod 17 from the outrigger seat 8, and then fix the reinforcing rod 17 back onto the positioning sleeve 15 for carrying.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
