Description
Technical Field
[0001] This invention relates to the field of special equipment for the production of energy-saving building materials, and more specifically to energy-saving cement pole forming equipment. Background Technology
[0002] In the construction of infrastructure such as power and communications, cement utility poles serve as key components supporting cables, and their structural rationality and production efficiency directly affect project quality and cost. Traditional cement utility poles mostly adopt a solid structure, which not only consumes a large amount of materials and has a high self-weight, increasing transportation and installation costs, but also has problems such as insufficient wind resistance. Therefore, the industry is gradually inclined to make utility poles with hollow structures to achieve the goals of weight reduction, material saving, and improved structural stability. Currently, mainstream equipment usually uses a method of setting a horizontal round rod (i.e., a core mold used to form the hollow cavity) in the mold for molding. During the molding process, concrete needs to be poured between the mold and the horizontal round rod. After the concrete initially sets, the horizontal round rod is removed to form the hollow cavity. However, due to the strong adhesion between the concrete and the surface of the horizontal rod during the solidification process, and the lack of specific anti-adhesion design in existing equipment, the following problems easily occur when the horizontal rod is pulled out: First, the surface of the horizontal rod adheres to the inner wall of the concrete, causing damage and cracking of the inner wall of the utility pole, affecting the product strength and appearance quality; Second, when the adhesion force is too large, a large external force is required to pull out the horizontal rod, which not only increases the difficulty of operation and energy consumption, but may also cause deformation of the mold or the horizontal rod due to uneven force, reducing the service life of the equipment. Summary of the Invention
[0003] To overcome the shortcomings of the existing technology, the present invention provides an energy-saving cement pole forming equipment, the beneficial effect of which is that the horizontal round rod can move left and right relative to the cylinder, making the pole into a hollow structure and preventing the horizontal round rod from sticking to the inside of the pole.
[0004] An energy-saving cement pole forming equipment includes two semi-cylinders arranged vertically to form a cylinder. Each semi-cylinder has a raised edge fixed on both its front and rear sides.

[0031] An energy-saving cement pole forming equipment includes a half-cylinder 101, with two half-cylinders 101 arranged vertically to form a cylinder. Each half-cylinder 101 has a raised edge 108 fixed on both its front and rear sides. Two positioning pins 109 are fixed on the two raised edges 108 on the lower side, with each positioning pin 109 inserted into the corresponding raised edge 108 on the upper side. A horizontal rod 105 is coaxially arranged inside the cylinder and can move left and right relative to the cylinder.
[0032] like Figure 5-6 As shown;
[0033] Two semi-cylinders 101 are assembled vertically to form a cylindrical mold. Precise alignment and positioning are achieved through positioning pins 109 on the raised edge 108, ensuring concentricity and sealing after the mold is closed. A horizontal rod 105, coaxially arranged inside the cylinder, serves as a core mold. During the concrete pouring and solidification process, a hollow structure is formed. While waiting for the concrete to solidify, the horizontal rod 105 can be continuously driven to move left and right relative to the cylinder, avoiding the adhesion problem caused by the fixed core mold in traditional equipment. At the same time, the movable design reduces the extraction resistance, achieving energy-saving and labor-saving effects.
[0034] Both ends of the horizontal cylindrical rod 105 are connected to ring plates 201, and the two ring plates 201 block the left and right sides of the cylinder respectively.
[0035] like Figure 5-8 As shown;
[0036] Both ends of the horizontal cylindrical rod 105 are fitted with ring plates 201. These ring plates 201 respectively block the left and right sides of the cylinder, forming a closed pouring space to prevent concrete from overflowing from the mold during pouring and molding. Simultaneously, the ring plates 201 limit the movement of the horizontal cylindrical rod 105, ensuring its coaxiality with the cylinder during pouring, guaranteeing the uniformity of the hollow structure of the utility pole, and avoiding uneven wall thickness caused by core mold misalignment.
[0037] Each of the four corners of the semi-cylinder 101 is fixed with a protrusion 102. The upper protrusion 102 and the lower protrusion 102 are fitted together. Two docking blocks 203 are fixed on the ring plate 201. The docking blocks 203 are provided with docking grooves. The docking blocks 203 are inserted into the corresponding two mating protrusions 102 through the docking grooves. The upper and lower sides of the docking blocks 203 are connected with fastening screws 202 by threads. Multiple fastening screws 202 are pressed on the corresponding protrusions 102 respectively.
[0038] like Figure 5-8 As shown;
[0039] After the protrusions 102 of the upper and lower half-cylinders 101 are fitted together, the mating block 203 on the ring plate 201 is inserted into the fitted protrusions 102 through the mating groove, and then tightened by the fastening screw 202, realizing a rigid connection between the ring plate 201 and the mold. This structure not only enhances the overall structural stability of the mold and prevents the mold from deforming due to concrete pressure during pouring, but also provides stable support for the horizontal rod 105 through the ring plate 201, ensuring its positional stability during vibration molding and other processes, further improving the product molding accuracy.
[0040] The ring plate 201 has a plurality of steel bar insertion holes 209 arranged in a ring shape.
[0041] like Figure 7-8 As shown;
[0042] Multiple reinforcing bar insertion holes 209 on the ring plate 201 are used to pre-insert reinforcing bars for the utility pole. The two ends of the reinforcing bars are fixed in the insertion holes of the left and right ring plates 201, forming a reinforcing bar skeleton that runs through the utility pole. This design allows the reinforcing bars to be positioned before pouring, ensuring the uniform distribution of the reinforcing bars in the concrete, enhancing the structural strength of the utility pole, and avoiding the positional deviation problem of traditional manual placement of reinforcing bars, thus improving production efficiency.
[0043] A feed pipe 104 is provided on the upper half cylinder 101. A plug 103 is inserted into the feed pipe 104. A fastening screw 110 is threadedly connected to the upper part of the plug 103. The fastening screw 110 can press against the feed pipe 104.
[0044] like Figure 5-6 As shown;
[0045] The feed pipe 104 of the upper half-cylinder 101 provides a channel for concrete pouring, facilitating accurate injection of concrete into the mold. After pouring, the feed pipe 104 is sealed by the plug 103 and secured with fastening screws 110 to prevent concrete from overflowing from the feed port during vibration molding. This structure simplifies the pouring process while ensuring the mold's airtightness, guaranteeing that the concrete fills the mold cavity under pressure.
[0046] A plate 107 is fixed to the lower side of the half-cylinder 101 located on the lower side. The plate 107 is inserted into the slot 307 on the upper side of the L-shaped frame 306. The lower part of the L-shaped frame 306 is fixed to the base 301.
[0047] like Figure 5-6 As shown in 9-10;
[0048] The insert plate 107 of the lower half-cylinder 101 engages with the slot 307 on the L-shaped frame 306, enabling quick positioning and installation of the mold and the base 301. The L-shaped frame 306 provides stable support for the mold, ensuring it remains level during pouring, vibration, and other processes, preventing uneven concrete distribution caused by mold wobbling. Simultaneously, the insert-type structure facilitates quick mold disassembly, making it convenient to remove the completed utility pole.
[0049] A boss 206 is fixed on the ring plate 201. Both ends of the rubber belt 208 are fixed on the boss 206. The rubber belt 208 is arranged in a ring on the outside of multiple steel bar insertion holes 209. A slide rod 205 is vertically slidably connected to the boss 206. A lifting block 207 is fixed at the lower end of the slide rod 205. The slide rod 205 is driven to slide by a hydraulic cylinder. Two round heads 204 are fixed on the lifting block 207. The two round heads 204 press against the outside of the two ends of the rubber belt 208 respectively.
[0050] like Figure 7-8 As shown;
[0051] The hydraulic cylinder can drive the slide rod 205 to slide up and down on the boss 206, thereby driving the lifting block 207 and the two round heads 204 to rise and fall. When multiple steel bars are inserted into multiple steel bar insertion holes 209, the ring structure formed by the rubber band 208 is set on the outside of the multiple steel bar insertion holes 209. After the two round heads 204 are driven to press on the outside of the two ends of the rubber band 208, the ring structure formed by the rubber band 208 will shrink, thereby making the rubber band 208 fit around the outside of the multiple steel bars, fixing the multiple steel bars on the ring plate 201, and preventing the multiple steel bars from moving left and right at will.
[0052] The base 301 is provided with a track 302, and the sliding sleeve 303 is slidably connected to the track 302 in the front-back direction. The sliding sleeve 303 is driven to slide by a hydraulic cylinder. A toggle plate 304 is fixed on the crossbar 308, and a hydraulic cylinder is fixed on the sliding sleeve 303. A gate-shaped component 305 is fixed to the movable end of the hydraulic cylinder, and the gate-shaped component 305 is inserted into the toggle plate 304.
[0053] like Figure 9-10 As shown;
[0054] The sliding sleeve 303 can slide back and forth on the track 302, thereby driving the horizontal bar 308 to move back and forth. The hydraulic cylinder can drive the gate-shaped component 305 to move left and right, thereby driving the toggle plate 304 to move left and right through the gate-shaped component 305, thereby driving the horizontal bar 308 to move left and right on the sliding sleeve 303, thus realizing the driving of the horizontal bar 308 to move back and forth and left and right.
[0055] Hollow plates 401 are fixed to both ends of the horizontal bar 308. A solid plate 407 is vertically slidably connected to the hollow plate 401. The solid plate 407 is driven to rise and fall by a hydraulic cylinder. A sliding column 405 is horizontally slidably connected to the upper part of the solid plate 407. A stop 406 is fixed to the outer end of the sliding column 405. A round seat 402 is fixed to the inner end of the sliding column 405. A compression spring is sleeved on the sliding column 405. The compression spring is located between the round seat 402 and the solid plate 407. Circular grooves 106 are provided at both ends of the horizontal bar 105. Two round seats 402 are respectively inserted into two circular grooves 106.
[0056] like Figure 11-12 As shown;
[0057] After the cylinder is connected to the L-shaped frame 306 via the insert plate 107, the drive sleeve 303 and the crossbar 308 are moved back and forth, causing the two hollow plates 401 to move to the left and right sides of the horizontal rod 105 respectively, and then causing the two solid plates 407 to move to the left and right sides of the horizontal rod 105 respectively. Then, the two round seats 402 are inserted into the two round slots 106 respectively, thus completing the docking of the two sliding columns 405 with the horizontal rod 105. At this time, the drive crossbar 308 is moved back and forth left and right, thus driving the two hollow plates 401 and the two solid plates 407 to move back and forth left and right. The two solid plates 407 drive the two round seats 402 to move left and right through the spring force of the compression spring, so that the horizontal rod 105 vibrates left and right continuously through the spring force. This prevents the horizontal rod 105 from sticking to the concrete of the utility pole while waiting for the concrete to solidify, and avoids the horizontal rod 105 from being difficult to separate from the utility pole. After the concrete has hardened, drive the two solid plates 407 to lift simultaneously, which in turn drives the two sliding columns 405 and the two round seats 402 to lift upwards, which in turn drives the horizontal round rod 105, the two semi-cylinders 101 and the utility pole to lift, so that the insert plate 107 leaves the L-shaped frame 306. At this time, the horizontal round rod 105 can be pulled out from the inside of the utility pole, and then the two ring plates 201 are removed. Then the two semi-cylinders 101 are separated vertically, and the utility pole can be taken out.
[0058] A hydraulic cylinder is fixed to the upper part of the solid plate 407, and a shift fork 404 is fixed to the movable end of the hydraulic cylinder. The shift fork 404 can move the stop head 406.
[0059] like Figure 11-12 As shown;
[0060] The hydraulic cylinder can drive the shift fork 404, which can push the stop 406 outward, thereby facilitating the separation between the two sliding pillars 405 and the two round seats 402, and thus facilitating the insertion or removal of the two round seats 402 into or out of the two round slots 106 on the horizontal round rod 105.
