[0032] Embodiment 1

[0033] The present embodiment provides a floating device for pouring pipe mounting head, the structure is shown in the accompanying drawings of the specification Figures 1-8 As shown, it specifically comprises a power head 100 for installing / dismantling the power of the pouring pipe 300, a floating device 200 detachably fixedly mounted below the power head 100, the floating device 200 comprises a first joint 1 and a second joint 2 floatingly connected with each other, the first joint 1 is connected with the power head 100, the second joint 2 is detachably connected with the pouring pipe 300 through threads, and the floating connection between the second joint 2 and the first joint 1 comprises axial movement and axial offset.

[0034] Structure and working principle:

[0035] Referring to Figure 7As shown, a power head 100 is arranged from top to bottom, which provides rotary power so that the pouring pipe 300 to be connected can be connected with another fixed pouring pipe 300 below through threads; the power head 100 is prior art, different power heads 100 have different structures, but from the classification of power supply modes, they can be divided into electric motor power and internal combustion engine power, and the power head 100 also includes a speed reduction and torque increasing gear structure for connecting with the pouring pipe 300. The power head 100 adopted in the embodiment can adopt existing mature technology.

[0036] The floating device 200 is one of the key technologies that distinguish the embodiment from the prior art. The existing power head 100 is directly rigidly connected with the pouring pipe 300 to be connected, and the connection mode is thread connection. The disadvantage of this rigid connection mode is that it is difficult to completely coaxially align the pouring pipe 300 with the power head 100, and in addition, the self-weight of the pouring pipe 300 is large, which cannot be aligned manually, so that the existing pouring pipe 300 needs two operators to cooperate during the alignment process. However, based on the different experiences of different operators, the tacit cooperation is different, which makes the pouring pipe 300 spend a lot of time during the connection and installation process. The embodiment creatively adds the floating device 200 between the power head 100 and the pouring pipe 300. The floating device 200 has the characteristics and advantages of floating allowance, so that the connection difficulty between the floating device 200 and the pouring pipe 300 is lower than that of the direct rigid connection between the power head 100 and the pouring pipe 300 in the prior art, thereby improving the connection efficiency.

[0037] During connection, the first joint 1 is fixedly connected with the power head 100, and the second joint 2 is floatingly connected with the first joint 1. The second joint 2 is connected with the pouring pipe 300 to be connected. Since the second joint 2 can reciprocally move along the axial direction and deflect and float relative to the first joint 1, the alignment difficulty of the pouring pipe 300 relative to the power head 100 is greatly reduced, the connection of the pouring pipe 300 and the second joint 2 is quickly completed, thereby improving the connection efficiency and shortening the connection time.

[0038] In terms of operation, since the existing connection mode of the end of the pouring pipe 300 is threaded connection; in addition, the second joint 2 is in a floating state, in order to avoid the occurrence of threaded silk slipping and tooth extraction during the connection process, before the second joint 2 is aligned with the pouring pipe 300, the power head 100 drives the entire floating device 200 to always be in a reverse rotation state, that is, in the opposite direction of tightening the pouring pipe 300. After hearing the regular "click" sound of silk slipping, the power head 100 is adjusted to forward rotation, so that the second joint 2 and the pouring pipe 300 can quickly establish a stable threaded relationship, and the end face of the pouring pipe 300 is in contact with the step structure 23 arranged at the bottom of the second joint 2.

[0039] Embodiment 2:

[0040] In order to further improve the strength and maintainability of the floating device under the premise of meeting the floating connection demand, so that the floating device can adapt to larger depth curtain wall pouring, further referring to the Figures 1-4 As shown in the figure, in this embodiment, the first joint 1 and the second joint 2 are coaxially installed, the second joint 2 is sleeved on the outer circumference of the first joint 1, the end of the first joint 1 away from the second joint 2 is provided with a flange plate for connecting the power head 100, the end of the second joint 2 close to the first joint 1 has a second flange 21 corresponding to the flange plate, and the flange plate and the second flange 21 are connected by floating bolts 3; the end of the second joint 2 away from the first joint 1 is a threaded sleeve 22 for connecting the pouring pipe 300.

[0041] In this embodiment, the floating bolts 3 are arrayed to connect the first joint 1 and the second joint 2, which has three advantages:

[0042] First, it can effectively establish a mechanical floating structure to improve the efficiency of aligning and connecting with the pouring pipe 300; second, it is convenient for subsequent maintenance and replacement of damaged parts; third, it is conducive to improving the strength of the entire floating device 200, so that it can carry out pouring of super-deep anti-seepage wall.

[0043] In order to further improve the precision of the pouring pipe alignment and the convenience of the operation, in the embodiment, the first joint 1 extends axially to the end face of the threaded sleeve 22 close to the second joint 2 to form a shaft shoulder 11, the alignment ring 5 is fixedly sleeved on the shaft shoulder 11, and the slope structure 51 for automatically aligning the pouring pipe 300 with the first joint 1 coaxially is arranged on the alignment ring 5; the radial width of the slope structure 51 gradually increases from one end close to the shaft shoulder 11 to the other end. The size of the alignment ring 5 is adapted to the internal structure of the end of the pouring pipe 300, the cross-sectional area of the end of the alignment ring 5 is minimum, and the cross-sectional area of the slope structure 51 in the tightening direction in the axial direction gradually increases, and this structure is the key structure for solving the quick alignment and maintaining the coaxiality of the pouring pipe 300 to be connected and the second joint 2. When the connection is just started, since the rotating direction of the power head 100 is the loosening direction of the pouring pipe 300, no matter how the pouring pipe 300 contacts the second joint 2, the two cannot be effectively connected together through the thread; however, due to the effect of the alignment ring 5, the shaft shoulder 11 can be easily inserted into the pouring pipe 300, and under the guidance of the slope structure 51 of the alignment ring 5, the pouring pipe 300 can naturally maintain the coaxial relationship with the second joint 2; after the alignment of the second joint 2 and the pouring pipe 300 is accurate, under the premise that the two abut against each other and the power head 100 is always reversed, since the thread cannot be matched, a "click" sound will be generated every time the relative rotation is one circle, at this time, the power head 100 can be rotated in the positive direction, and the second joint 2 and the pouring pipe 300 can be quickly connected.

[0044] As an optional floating structure, in the embodiment, the floating bolt 3 includes a screw rod penetrating through the flange plate and the second flange 21, the limiting sleeve 31 is arranged on the screw rod and located between the flange plate and the second flange 21 and between the nut and the second flange 21, respectively, and the spring 4 is sleeved on any limiting sleeve 31. The screw rod is provided with the spring 4 at both ends of the second flange 21, and the advantage of this structure is that the supporting capacity is strong, the number of the springs 4 participating in the floating action is large, and the bearing capacity of the floating device 200 is better; the requirement for the tightness adjustment of the single floating bolt 3 is relatively low; and the disadvantage is that the number of the springs 4 required is large, the number of periodical maintenance and replacement is more, and the subsequent maintenance cost is relatively high.

[0045] The utility model also provides another floating structure, specifically, the floating bolt 3 includes a screw rod penetrating through the flange plate and the second flange 21, the limiting sleeve 31 is arranged on the screw rod and located between the flange plate and the second flange 21 and between the nut and the second flange 21, respectively, and the spring 4 is sleeved on any limiting sleeve 31. The screw rod is provided with the spring 4 at both ends of the second flange 21, and the advantage of this structure is that the supporting capacity is strong, the number of the springs 4 participating in the floating action is large, and the bearing capacity of the floating device 200 is better; the requirement for the tightness adjustment of the single floating bolt 3 is relatively low; and the disadvantage is that the number of the springs 4 required is large, the number of periodical maintenance and replacement is more, and the subsequent maintenance cost is relatively high. Figures 1-2The joint shown will be significantly cheaper than the large number of spring 4 mounting schemes provided above; but the pre-tightening force requirement for each floating bolt 3 is higher, and it must be ensured that the stress of each spring 4 in the initial state is the same and within a preset range value, otherwise the floating effect will be reduced.

[0046] For axial floating, it is dependent on the compression of the spring 4 to realize the relative axial movement of the first joint 1 and the second joint 2, as shown in Figure 6 For deflection floating, it is realized by the uneven compression of the arrayed multiple springs 4 and the gap between the screw rod and the flange plate and the second flange 21 to realize the deflection between the flange plate and the second flange 21, as shown in Figure 5 the deflection angle β shown.

[0047] Embodiment 3:

[0048] The embodiment also provides a floating device with an improved power head 100, as shown in the accompanying drawings of the specification Figure 7 and Figure 8 The power head 100 includes a fixed shaft 104 fixedly connected with a support of a gantry or a pouring pipe installation device, a motor 101 fixedly installed on the gantry or the fixed shaft 104, and a large gear 106 rotatably connected with the fixed shaft 104 through a bearing 103, as shown in Figure 9 The output shaft of the motor 101 is provided with a driving gear 102 and is engaged with the large gear 106 to drive the large gear 106 to rotate forward or reverse; and the lower end surface of the large gear 106 is fixedly connected with a first flange 105 for connecting the floating device 200. In order to improve the practical range and reliability of the utility model, the number of the motor 101 is two, which simultaneously or alternatively drives the large gear 106. When the pouring pipe 300 is stuck, a larger torque is required for disassembling the pouring pipe 300, so two motors 101 can be used to simultaneously drive and quickly realize the disassembly of the pouring pipe 300; in addition, if one of the motors 101 fails in the actual construction process, the other standby motor 101 can be used to replace the work without stopping, thereby effectively avoiding the interruption of the supply of concrete for the curtain grouting caused by the equipment failure and avoiding the negative impact on the overall performance of the waterproof curtain. It is worth noting that in order to obtain greater driving force and greater driving torque, the motor 101 can also be replaced by a hydraulic motor.

[0049] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
