Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to an installation tool for an attachment frame of a tower crane. Background Art

[0002] The attachment device is an important structural part of the tower crane, which plays an important role in resisting external forces, improving the tower strength and maintaining the stability of the tower crane. The attachment device consists of an attachment frame, a wall mount and an attachment rod, and the attachment frame consists of four L-shaped steel beams. When installing the attachment device of the tower crane, the L-shaped steel beams need to be connected in sequence to form an attachment frame that fits tightly with the standard section, and the attachment frame is connected and fixed to the building through attachment rods.

[0003] In actual construction, whether it is to determine the exact position of the attachment frame or the exact position of the attachment rod first, it is necessary to lift the L-shaped steel beam by manpower, straighten the L-shaped steel beam that is lifted by the wire rope to an approximate height to a horizontal direction (that is, adjust the two end arms of the L-shaped steel beam to the same horizontal height), lift it to the accurate installation height, and then connect and fix it. However, the mass of the L-shaped steel beam is relatively large. Generally, a single L-shaped steel beam requires at least 5 operators to twist and lift it. Its installation efficiency is too low, the labor consumption is huge, and there are also great safety hazards. The bottom of the L-shaped steel beam has no other support except manual lifting. Once the suspension rope breaks, it is very easy to cause the L-shaped steel beam to fall and cause an object impact accident. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] Example 1

[0023] Reference Figure 1-3 , an installation tool for a tower crane attachment frame, comprising a standard section hoop 1, a steel beam bracket 2, an anti-slip block 3, a connector 4 and a diagonal brace 5, the steel beam bracket 2 is a horizontally placed plate, the standard section hoop 1 and the anti-slip block 3 are respectively arranged at opposite ends of the steel beam bracket 2, and the anti-slip block 3 is located at the top of the steel beam bracket 2; a plurality of standard section hoops 1 are provided, and the plurality of standard section hoops 1 are coaxially distributed up and down, each standard section hoop 1 comprises an annular plate 1-1 and an annular plate 2 1-2 which are concavely opposite and detachably connected, the adjacent annular plates 1-1 are connected by a connector 4, and the connector 4 is connected to the bottom surface of the steel beam bracket 2 by a diagonal brace 5.

[0024] When installing the component of the tower crane attachment frame - the L-shaped steel beam 12, first put the standard section clamp 1 on the outside of the standard section column 6, adjust the height of the standard section clamp 1 so that the steel beam bracket 2 is located at the accurate installation height of the L-shaped steel beam 12, and lock the standard section clamp 1; then use a sling to lift the L-shaped steel beam 12 to the erection steel beam bracket 2, and manually only need to rotate the direction of the L-shaped steel beam 12 and connect and fix the attachment frame. The anti-slip block 3 arranged at the end of the steel beam bracket 2 away from the standard section clamp 1 can effectively prevent the L-shaped steel beam 12 from slipping; the standard section clamp 1 is installed at the accurate height in advance, and the L-shaped steel beam 12 is supported by the steel beam bracket 2. For high-altitude operations, although the pre-installation and adjustment work of the installation tool is increased, the installation tool is light in weight (compared to the L-shaped steel beam 12 itself), easy to install and disassemble, and will not bring too much construction burden, and can effectively reduce the labor cost of lifting the L-shaped steel beam 12 at high altitude in the later stage, which can not only improve construction efficiency and save labor costs, but also reduce the safety risks of high-altitude workers.

[0025] In this embodiment, the connecting member 4 adopts an arc-shaped plate with the same arc as the annular plate 1-1 to closely fit the outer wall of the standard section column 6, and the diagonal support member 5 adopts a right-angled triangle plate with the hypotenuse facing downward to enhance the supporting stability and structural stability of the device.

[0026] In this embodiment, the two ends of the annular plate 1-1 extend radially outward to form connecting plates 1-3, and the two ends of the annular plate 1-2 extend radially outward to form connecting plates 1-4. The connecting plates 1-3 and 1-4 are connected by high-strength bolts. When in use, the annular plate 1-1 and the annular plate 1-2 are first arranged on the outside of the standard section column 6, and the two are pre-connected by high-strength bolts, that is, they are connected but not tightened. After the standard section clamp 1 is slid along the standard section column 6 to a precise height, the high-strength bolts are tightened. The installation, disassembly and adjustment operations are very simple.

[0027] In order to improve the connection and support stability, the present embodiment also provides anti-skid gaskets 7 on the concave sides of the annular plate 1 - 1 and the annular plate 2 1 - 2 to increase the friction between the standard section clamp 1 and the standard section column 6 .

[0028] During implementation, the installation tools provided in this embodiment can be used in groups. Generally, there are four standard section columns 6. A set of this installation tools can be pre-installed and adjusted on each standard section column 6, and then the next step of lifting and connecting the L-shaped steel beam 12 can be carried out to save time waste caused by frequent alternation of different construction links and improve construction safety.

[0029] Example 2

[0030] Reference Figure 4, the difference from the embodiment 1 is that the connecting member 4 in this embodiment includes a travel rod 8 and a stop block 9, at least one end of the travel rod 8 is slidably connected to the annular plate 1-1, for example, the top end is slidably inserted into the annular plate 1-1 above the travel rod 8, or the bottom end is slidably inserted into the annular plate 1-1 below the travel rod 8, or the top end and the bottom end are respectively slidably inserted into the annular plates 1-1 on both sides of the travel rod 8; the stop block 9 is sleeved on the travel rod 8 and threadedly connected thereto, and the number of the stop rods is configured according to the number of the annular plates 1-1 slidably connected to the travel rod 8, that is, each annular plate 1-1 slidably connected to the travel rod 8 is at least abutted against one stop block 9, and the stop block 9 is located between adjacent annular plates 1-1. The diagonal brace 5 adopts a telescopic rod, and its two ends are respectively hinged to the travel rod 8 and the steel beam bracket 2.

[0031] In terms of usage, the difference from Example 1 is that this embodiment can first fix the standard section clamp 1 located below, and then adjust the distance between another standard section clamp 1 and the aforementioned fixed standard section clamp 1 by rotating and changing the height of the limit block 9 on the travel rod 8, thereby changing the height of the steel beam bracket 2, thereby achieving precise and timely adjustment of the height of the steel beam bracket 2. Because if multiple groups of standard section clamps 1 are fixed and height deviations are found when the method of Example 1 is used, it is also necessary to loosen the high-strength bolts on all standard section clamps 1 before sliding the installation tool of the entire attachment frame. In comparison, the operation of this embodiment is simpler.

[0032] Example 3

[0033] Reference Figure 4 , which is different from Example 2, is that in this embodiment, sleeves 10 and inner tubes 11 are fixed on opposite sides of adjacent annular plates 1-2, respectively. The inner tube 11 is slidably inserted into the sleeve 10. When the position of the limit block 9 is adjusted to change the spacing between adjacent annular plates 1-1, the length of the inner tube 11 extending into the sleeve 10 changes accordingly. On the one hand, the friction between the inner tube 11 and the sleeve 10 can improve the connection tightness of the two sets of standard section clamps 1. On the other hand, the inner tube 11 is slidably connected to the sleeve 10, which does not affect the height adjustment of the limit block 9.

[0034] Compared with the prior art, the beneficial effects of the utility model are: providing an installation tool for a tower crane attachment frame that is easy to install and adjust; compared with the traditional high-altitude multi-person lifting of an L-shaped steel beam 12, the installation tool can save manpower, improve construction safety and the accuracy of the installation height of the attachment frame; and after use, the tool is easy to remove from the standard section for turnover, and the construction economy is high.

[0035] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
