The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The utility model discloses a first embodiment discloses a keel support 10. As shown in fig. 3, the cylindrical equipment 1 is used for manufacturing glass fiber reinforced plastic pipes. The keel support 10 is a flat, disc-like structure. The outer shape of which can be set as desired. For example, to make a cylindrical barrel, the keel support 10 may be disc-shaped. To make a square cartridge, the keel support 10 may be square or rectangular disc-shaped. The keel support 10 is described below as a disc.

Figure 1 illustrates a keel support 10 according to one embodiment of the invention. The keel support 10 is composed of a plurality of fan-shaped support portions 101. The keel support 10 shown in fig. 1 is made up of four fan-shaped support portions 101. The following description will be given taking four fan-shaped bracket portions 101 (also referred to as right-angle fan-shaped portions) as an example. It should be understood by those skilled in the art that the scope of the present invention is not limited to four quadrant shaped support sections. Under the enlightenment of the utility model, the ordinary technical personnel can conceive the fan-shaped support portion of other numbers for solve the technical problem of the utility model, realize the technical purpose of the utility model. Such variations are within the scope of the claims of the present invention. For example, the keel support 10 may be constructed with three 120 degree support portions, each having a wedge 107 disposed therebetween to urge the three support portions toward or away from the center of the keel support.

The construction of the keel support 10 is described in detail below with reference to figures 1 and 2.

As shown in fig. 1, the keel support 10 is formed of four support portions 101, each support portion 101 is substantially in the shape of a 90-degree right-angle sector made of, for example, 7075 high-strength standard aluminum alloy. Referring to fig. 1 and 2, the four sectorial bracket portions 101 are formed into two groups, the first group being two upper sectorial bracket portions 101 (first bracket portions), and the second group being two lower sectorial bracket portions 101 (second bracket portions). Fig. 2 shows the upper two quadrant bracket parts 101. Taking the above two bracket portions 101 as an example, the two bracket portions are connected to each other by bolts, nuts, and bolt connectors.

The structure of the holder portion 101 is described with reference to fig. 2. As shown in fig. 2, the bracket portion 101 is substantially in the shape of a right-angled sector having a first radial portion 1011 and a second radial portion 1012. The first radial portion 1011 and the second radial portion 1012 are substantially perpendicular and are integral or connected at one end. Between the other ends of the first and second

radial portions

1011, 1012, an arcuate edge 1013 is connected, forming substantially a right-angled sector, forming a mechanically stable structure capable of withstanding compression and tension. Optionally, the bracket portion 101 further includes a stiffening rod 1014 having one end connected to or integral with the first radial portion 1011 and/or the second radial portion 1012 and another end connected to or integral with the arcuate edge 1013, such as at about a middle of the arcuate edge 1013, to improve stability of the bracket portion 101. By forming the bracket portion 101 from the first radial portion 1011, the second radial portion 1012, the arc-shaped edge 1013, and the reinforcing rod 1014, the entire bracket portion 101 can satisfy the requirements in terms of mechanics and strength. It is also preferred that a cavity be formed between the first radial portion 1011 and the stiffener 1014, and a cavity be similarly formed between the second radial portion 1012 and the stiffener 1014, which greatly reduces the weight of the bracket portion 101 while meeting the strength requirements.

One or more through or threaded holes may be provided in the first radial portion 1011, the second radial portion 1012 and the reinforcement bar 1014 for interconnection between the frame portions 101 or for connection to other components of the barrel manufacturing apparatus 1. For example, a plurality of through holes are distributed on the second radial portion 1012, and bolts or screws 110 are passed therethrough, thereby fixing two adjacent bracket portions 101 together. A plurality of through holes 1015 may be further disposed at a lower end of the second radial portion 1012 for connecting the upper and lower sets of fan support portions 101. The function of which will be described in detail below.

To further reduce weight, the stiffener 1014 may be provided with one or more cavities along its length. The stiffener 1014 is shown in fig. 2 with a cavity provided therein. Alternatively, a plurality of cavities may be provided in the arcuate edge 1013 along the direction of its arc. Preferably, the cavities on the arcuate edge 1013 are evenly distributed so that the force distribution is more uniform. Although not shown in fig. 2, one of ordinary skill will appreciate that cavities may also be provided in first radial portion 1011 and second radial portion 1012 to further reduce their weight.

The arcuate edge 1013 has a plurality of slots 1016 uniformly distributed along its periphery. The catch 1016 is for receiving a rafter 1016'. In fig. 3, rafters 1016' have a lengthwise direction parallel to drive shaft 2 and perpendicular to keel support 10. Referring to fig. 3, a plurality of elongate rafters 1016' are received in the pockets 1016 to bridge the spacing between adjacent keel supports 10 to form a drum onto which winding may be performed, for example, to wind glass fibre reinforced plastic. Preferably, to avoid excessive reduction in the structural rigidity of the arcuate edge 1013 by the slots 1016 and cavities on the arcuate edge 1013, the slots 1016 and cavities are offset from one another, e.g., the slots 1016 are spaced between adjacent cavities. The purline, the material can be hard miscellaneous wood for example, installs in the draw-in groove of fossil fragments support outer fringe, leads to long with the main shaft is parallel, and its effect is the reinforcing hoop atress.

One end of the arc-shaped edge 1013 may also be provided with a plurality of through holes 114 for connecting the adjacent bracket parts 101. Two through holes 114 are shown in fig. 2. As shown in fig. 1, when the adjacent two bracket portions are aligned, the bolt connecting member 109 having the through-hole is overlaid on the arc-shaped edge 1013 so that the through-hole of the bolt connecting member 109 coincides with the through-hole 114, and the bolt 110' is inserted thereinto and fixed.

Therefore, two adjacent fan-shaped support portions 101 are fixed together by the through holes 114, the bolt connectors 109 and the bolts on the second radial portion 1012 to form an upper set of fan-shaped support portions, and the joint of the arc-shaped edges of the two fan-shaped support portions forms a clamping groove 1016.

In the same way, a lower set of sector-shaped support parts can be formed.

In fig. 1, the upper set of two fan shaped bracket portions 101, alternatively, may be a unitary fan shaped bracket portion having a fan shape with an angle of approximately 180 degrees. The lower set of fan support sections 101 may likewise be an integral fan support section.

How the upper and lower sets of quadrant segments are connected together is described below with reference to figure 1.

In the vertical direction in fig. 1, the upper and lower sets of sector-shaped bracket portions 101 are connected together by one or more guide and positioning rods 106 (e.g., telescopic rods). Preferably, a plurality of guide positioning rods are provided and arranged in bilateral symmetry in fig. 1, so as to improve the connection stability of the two sets of sector bracket portions 101. Fig. 1 shows four guide and positioning rods 106, two on the left and right.

As previously described with reference to fig. 1 and 2, a plurality of through-holes or threaded holes may be provided on the first radial portion 1011. Both ends of the guide positioning rod 106 can be fixed to the first radial portion 1011 by passing a screw through the through hole, as shown in fig. 1.

The guide positioning rod 106 moves between two extreme positions: a tension limit and a compression limit. Preferably, the guide positioning rod 106 has elasticity to contract to the compression limit. Therefore, the guide positioning rod 106 pulls the upper and lower sets of fan-shaped bracket portions 101 toward each other. Meanwhile, because the guiding and positioning rod 106 can only move between two limit positions and cannot exceed the two limit positions, the guiding and positioning rod 106 also provides a limit function for the two groups of fan-shaped bracket parts 101 above and below, so that the distance separating the two cannot exceed a certain limit, and the approaching degree of the two cannot exceed a certain distance.

The guide positioning rod can have various structures, such as a spring, a hydraulic rod, an air stay rod and the like. The guiding and positioning rod 106 comprises a main rod and a loop bar, the main rod comprises two cylinders with different diameters, the cylinders are relatively fixed and arranged on the fan-shaped support, the loop bar is sleeved on the cylinder with the smaller diameter of the main rod to realize stretching, and a step between the two cylinders of the main rod plays a limiting role.

The keel support 10 also includes a driving bushing 113 disposed between the upper and lower sets of support portions 101. The transmission shaft 2 passes through the transmission shaft sleeve 113 and drives the transmission shaft sleeve 113 to rotate together, so as to drive the whole keel support 10 to rotate. The transmission shaft 2 and the transmission shaft sleeve 113 can be connected in various ways, such as bolt connection, interference fit, key connection and the like, so that synchronous rotation of the transmission shaft and the transmission shaft sleeve is realized.

The driving sleeve 113 is connected above by means of the telescopic mechanism 112 to the upper set of sector-shaped supporting parts and below by means of the telescopic mechanism 112 to the lower set of sector-shaped supporting parts. Preferably, similar to the guide positioning rod 106, the retractable mechanism 112 may be a spring, hydraulic rod, air stay, or the like, and has a tendency to retract, thereby helping to pull the upper and lower quadrant 101 toward each other. Taking a hydraulic cylinder as an example, the retractable mechanism 112 includes hydraulic cylinders 105 respectively fixed on the upper and lower sets of fan-shaped support portions.

As previously described, a plurality of through holes 1015 may also be provided at the lower end of the second radial portion 1012. In fig. 1 and 2, the retractable mechanism 112 is connected to the upper and lower fan support portions 101 through the plurality of through holes 1015, and screws penetrating through the through holes 1015.

Of course, the upper and lower sets of sector-shaped support portions 101 may be pulled towards each other only by the telescopic mechanism 112, and the guide positioning rod 106 does not exert a pulling action in the vertical direction, but only provides a guiding action in the vertical direction.

By the interaction of the telescopic mechanism 112 and the guide positioning rod 106, the upper and lower sets of sector-shaped support portions 101 can only move relatively in the vertical direction in fig. 1, but cannot move relatively in the horizontal direction in fig. 1.

In FIG. 1, the outdrive 113 is also coupled to or integrally formed with a carrier 102. The bracket 102 extends in a generally horizontal direction in fig. 1, is symmetrical about the outdrive 113, and is located between the upper and lower sets of sector-shaped bracket portions 101. Hydraulic mechanisms may be provided at the left and right ends of the bracket 102, respectively. The hydraulic cylinder 104 of the hydraulic mechanism is fixedly arranged at both ends of the bracket 102, and the ram 108 of the hydraulic mechanism extends out of the hydraulic cylinder 104 and is connected with the wedge block 107.

As shown in fig. 1, the wedge 107 is trapezoidal in shape, for example made of 45 steel. The portion of the wedge 107 closer to the outdrive 113 is larger in size and the portion further from the outdrive 113 is smaller in size. When the hydraulic cylinder 104 is filled with hydraulic oil, the ram 108 is further extended, pushing the wedge 107 outwards, i.e. away from the outdrive 113. When hydraulic fluid is drained from the hydraulic cylinder 104, the ram 108 retracts, causing the wedges 107 to move inwardly, i.e., toward the outdrive 113.

As shown in fig. 1 and 2, the outer end of the first radial portion 1011 of the bracket portion 101 has an inclined surface 1017. The inclination of the inclined surface 1017 matches the inclination of the wedge 107 so that the two can be brought into close contact and can perform a sliding movement with respect to each other.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
