Description

Technical Field

[0001] The invention belongs to the technical field of workpiece turning over, and in particular relates to a hydraulic turning machine for precast concrete parts. Background Art

[0002] Precast concrete parts refer to concrete products that are processed and produced in a standardized and mechanized manner in a factory. In contrast, traditional cast-in-place concrete requires on-site molding, pouring and maintenance. Precast concrete parts are widely used in the fields of construction, transportation, water conservancy, etc. The use of precast concrete components for assembly construction has the advantages of saving labor, overcoming seasonal influences, and facilitating year-round construction.

[0003] Existing precast concrete parts need to be turned over during the processing process to turn the concrete over as a whole, so as to facilitate the operator to process different surfaces of the precast concrete parts.

[0004] However, it was found during the use of the existing turning machine that due to the large size of the precast concrete parts, when the turning machine performs the turning operation, the precast concrete parts need to be lifted first to separate the precast concrete parts from the support platform to ensure that the precast concrete parts will not contact the support platform during the turning process before they can be turned over. After the turning is completed, the precast concrete parts need to be moved down again to contact the support platform to ensure the stability of the precast concrete parts after turning over. In the above operation, the movement of the support platform needs to be controlled separately, which is more troublesome. In addition, in the actual operation, the precast concrete parts are heavy, so lifting the precast concrete parts requires greater energy consumption, which increases the energy consumption of the turning machine and increases the cost.

A side plate 205 is arranged at the end of the slide rod 2042. A combined slide groove is opened on the side plate 205, and the slide rod 2042 slides on the combined slide groove. The side wall of the side plate 205 and the output end of the hydraulic push rod body 206 fixed on the base 101 are connected to each other; the combined slide groove includes a separation slide groove 2051, a flip slide groove 2052 and a support slide groove 2053, the flip slide groove 2052 is a linear slide groove, and the support slide groove 2053 and The separation chutes 2051 are all inclined chutes; when the hydraulic push rod body pushes the side plate upward, the slide bar on the fixed plate slides on the separation chute, and drives the fixed plate as a whole to move outward through the inclined separation chute, and finally slides onto the flip chute. When the fixed plate moves, the fixed plate drives the slide plate to slide, and drives the end support plate to move downward through the installed swing arm, and the support plate moves downward and is separated from the precast concrete plate. The prior art is to lift the precast concrete plate and move it upward to complete the separation operation. Therefore, in comparison, the energy consumption of this setting is smaller, and the hydraulic push rod body can also drive the flip unit to move. The purpose of separating and flipping the support plate can be achieved by starting the hydraulic push rod, and the operation is simpler.

When the hydraulic push rod body pushes the side plate to rise, the fixed plate moves to the separation slide groove and squeezes the insertion rod, which drives the first piston to slide inside the energy storage sleeve, and drives the lifting plate to move through air pressure, so that the lifting plate and the lifting protrusion are located on the same plane. As the side plate continues to move upward, the lifting plate pushes the lifting protrusion to rotate, and drives the driving gear and the driven gear to rotate, so that the precast concrete slab installed on the mounting plate can rotate, achieving the purpose of flipping. After the first degree of flipping, the support plate is moved up through the supporting slide groove, and the precast concrete slab is supported again to ensure the stability of the precast concrete slab.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, a non-slip pad 1011 is installed at the bottom of the base 101, four positioning holes 1012 are opened at the corners of the base 101, a pair of enclosures 104 are installed on the base 101, and the side walls of the pair of enclosures 104 are both provided with mounting ears 1041, and the mounting ears 1041 are screwed and connected to the side of the vertical plate 102 by bolts. The non-slip pad 1011 increases the stability of the equipment, and the enclosure 104 serves the purpose of protection.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, further, a protective cover 103 is provided on the base 101, one side of the protective cover 103 contacts the vertical plate 102, and the protective cover 103 covers the outside of the push plate 304, the fixing plate 204 and the side plate 205. A positioning plate 1032 is provided at the bottom of the protective cover 103, and bolts are screwed on the positioning plate 1032 and the base 101, and an inspection door 1031 is installed on the protective cover 103. The protective cover 103 serves the purpose of protection, and the inspection door 1031 facilitates the later inspection and maintenance operations. Example 2

[0026] The difference between the above embodiment and this embodiment is that: Figure 3 and Figure 5 As shown, a support seat 2011 is installed on the top of the support plate 201, the bottom of the support seat 2011 and the bottom of the precast concrete slab 400 overlap each other, the swing arm 2012 is in an inclined state, and a pair of swing arms 2012 are in a herringbone shape, and the support plate 201 is slidably arranged in the cavity surrounded by the enclosure 104 and the vertical plate 102. During the horizontal outward movement of the fixed plate 204, the slide plate 202 slides synchronously, and drives the support plate 201 connected at the end to move downward through the herringbone swing arm 2012, and the downward movement of the support plate 201 releases the support of the precast concrete slab 400 on the top of the support seat 2011, facilitating the subsequent flipping operation.

[0027] like Figure 3 and Figure 5 As shown, in a specific embodiment, a push rod 203 is installed at the bottom of the support plate 201, a positioning sleeve 2031 is slidably provided at the bottom of the push rod 203, and the positioning sleeve 2031 is installed on the base 101, a baffle 2033 is slidably provided inside the positioning sleeve 2031, the top of the baffle 2033 and the push rod 203 are connected to each other, a return spring 2032 is clamped between the bottom of the baffle 2033 and the bottom of the positioning sleeve 2031, and the compression direction of the return spring 2032 is the same as the movement direction of the push rod 203. When the support plate 201 slides downward, the support plate 201 drives the push rod 203 at the bottom to slide into the positioning sleeve 2031, and the baffle 2033 at the end of the push rod 203 slides downward, and the baffle 2033 compresses the return spring 2032, and the return spring 2032 facilitates the reset operation later.

[0028] like Figure 3 and Figure 5As shown, further, the slide plate 202 movably penetrates the side wall of the vertical plate 102, the bottom of the slide plate 202 is slidably connected to the base 101, the side wall of the slide plate 202 is fixedly installed with a limit plate 2021, and the limit rod 2022 is movably installed on the limit plate 2021, and the two ends of the limit rod 2022 are respectively connected to the side walls of the vertical plate 102 on both sides. During the movement of the slide plate 202, the slide plate 202 slides inside the vertical plate 102, and the limit plate 2021 of the side wall of the slide plate 202 slides inside the limit rod 202, and the horizontal movement of the slide plate 202 is guaranteed by the horizontal limit rod 202. Example 3

[0029] The difference between the above embodiment and this embodiment is that: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the height of the end of the separation slide groove 2051 close to the side of the vertical plate 102 is higher than the height of the other end, the height of the end of the support slide groove 2053 close to the side of the vertical plate 102 is higher than the height of the other end, the position of the flip slide groove 2052 corresponds horizontally to the insertion rod 3051, and the length of the flip slide groove 2052 is smaller than the radius of the driving gear 3021.

[0030] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in a specific embodiment, a through groove is provided inside the push plate 304, and a partition 3041 is installed inside the through groove, the force storage sleeve 305 is installed on the partition 3041, a compression spring 3054 is installed inside the force storage sleeve 305, and the compression direction of the compression spring 3054 is the same as the moving direction of the insertion rod 3051, and an extrusion block 3052 is installed on the insertion rod 3051 located outside the force storage sleeve 305, and the surface of the extrusion block 3052 is chamfered. After the extrusion block 3052 moves upward, it will contact the side wall of the fixed plate 204, and then push the extrusion block 3052 to slide inside the force storage sleeve 305, and the insertion rod 3051 drives the first piston 3053 to slide, compressing the compression spring 3054, and the compression spring 3054 is convenient for later reset. When the first piston 3053 slides, the first piston 3053 squeezes the gas inside the force storage sleeve 305.

[0031] like Figure 5 , Figure 6 and Fig.10As shown, further, the connecting pipe 306 is movably inserted into the notch 2041 opened on the surface of the fixed plate 204, and a connecting plate 3062 is installed on one side of the sliding sleeve 3061, and the end of the connecting plate 3062 is connected to the side wall of the side plate 205, and a synchronous plate 3063 is installed on the other side of the sliding sleeve 3061. The gas squeezed by the inner wall of the power storage sleeve 305 moves outward through the connecting pipe 306, and the end of the connecting pipe 306 is connected to the second piston 3072. At this time, the second piston 3072 pushes the plug plate 3071 to move outward, and the lifting plate 307 on the plug plate 3071 moves to the same plane as the lifting protrusion 3031.

[0032] like Figure 3 and Figure 4 As shown, further, flat plates 3011 are installed on both sides of the mounting plate 301, and the first fixing plate 3012 and the second fixing plate 3013 are installed on the flat plates 3011 respectively, the second fixing plate 3013 is located below the first fixing plate 3012, and the precast concrete plate 400 is overlapped on the second fixing plate 3013, and the first fixing plate 3012 is screwed with a locking bolt 3014, and the end of the locking bolt 3014 is tightly fitted with the precast concrete plate 400. The precast concrete plate 400 is placed on the second fixing plate 3013, and the locking bolt 3014 is screwed on the first fixing plate 3012 at this time, and the precast concrete plate 400 and the first fixing plate 3012 and the second fixing plate 3013 are connected and locked with each other through the locking bolt 3014, so as to achieve the purpose of clamping and fixing.

[0033] The implementation principle of a hydraulic turning machine for precast concrete parts in this embodiment is as follows: First, the operator needs to place the precast concrete panel 400 on the second fixing plate 3013, and at this time, the locking bolts 3014 are screwed on the first fixing plate 3012, and the precast concrete panel 400 and the first fixing plate 3012 and the second fixing plate 3013 are connected and locked to each other through the locking bolts 3014, thereby achieving the purpose of clamping and fixing.

[0034] Then the operator starts the hydraulic push rod body 206 and turns the clamped precast concrete panel 400 through the hydraulic push rod body 206 .

[0035] The hydraulic push rod body 206 pushes the push plate 304 and the side plate 205 to move upward synchronously, and the force storage sleeve 305 and the connecting pipe 306 installed on the push plate 304 move upward synchronously, and the combined slide groove on the side plate 205 slides upward synchronously. First, the slide rod 2042 slides in the inclined separation slide groove 2051. As the side plate 205 drives the separation slide groove 2051 to slide upward, it drives the horizontally constrained fixed plate 204 to start moving to both sides, and the fixed plate 204 finally moves along the separation slide groove 2051 to the flip slide groove 2052.

[0036] At the same time, the connecting pipe 306 moves to the bottom of the lifting protrusion 3031.

[0037] During the horizontal movement of the fixed plate 204, the slide plate 202 slides synchronously, and drives the support plate 201 connected at the end to move downward through the herringbone swing arm 2012. The downward movement of the support plate 201 releases the support for the precast concrete slab 400 on the top of the support seat 2011, thereby facilitating the subsequent flipping operation.

[0038] During the movement of the slide plate 202 , the slide plate 202 slides inside the vertical plate 102 , and the limiting plates 2021 on the side walls of the slide plate 202 slide inside the limiting rods 2022 , and the horizontal movement of the slide plate 202 is ensured by the horizontal limiting rods 2022 .

[0039] As the support plate 201 slides downward, the support plate 201 drives the bottom push rod 203 to slide into the positioning sleeve 2031, and the baffle 2033 at the end of the push rod 203 slides downward, and the baffle 2033 compresses the reset spring 2032, and the reset spring 2032 facilitates the subsequent reset operation.

[0040] After the precast concrete slab 400 is released from support, the hydraulic push rod body 206 is continued to be started, and at this time, the hydraulic push rod body 206 drives the push plate 304 and the side plate 205 to continuously move upward.

[0041] After the side plate 205 moves upward, the slide bar 2042 slides inside the vertical flip slide groove 2052, and the fixed plate 204 remains stationary, thereby ensuring that the support plate 201 is always in an unlocked state.

[0042] After the push plate 304 moves upward, the force storage sleeve 305 and the insertion rod 3051 on the push plate 304 move. At this time, the extrusion block 3052 at the end of the insertion rod 3051 will contact the side wall of the fixed plate 204, and then push the extrusion block 3052 to slide into the force storage sleeve 305, and the insertion rod 3051 drives the first piston 3053 to slide, compressing the compression spring 3054, and the compression spring 3054 is convenient for later resetting. When the first piston 3053 slides, the first piston 3053 squeezes the gas inside the force storage sleeve 305.

[0043] At this time, the squeezed gas moves outward through the connecting pipe 306, and the second piston 3072 is connected to the end of the connecting pipe 306. At this time, the second piston 3072 pushes the plug plate 3071 to move outward, and the lifting plate 307 on the plug plate 3071 moves to the same plane as the lifting protrusion 3031. As the connecting pipe 306 moves upward, the lifting protrusion 3031 is pushed upward, thereby driving the turntable 303 installed with the lifting protrusion 3031 to rotate, so that the coaxially connected driving gear 3021 rotates, and the small-sized driven gear 302 is driven to rotate through the driving gear 3021, ensuring that the driven gear 302 rotates one circle, thereby driving the mounting plate 301 to rotate one circle, so that the precast concrete slab 400 installed on the mounting plate 301 rotates one circle, which has the effect of turning over.

[0044] After the flipping is completed, the slide bar 2042 moves to the connection between the flipping slot 2052 and the supporting slot 2053. As the side panel 205 slides upward, the slide bar 2042 moves to the supporting slot 2053 and separates from the extrusion block 3052, thereby driving the lifting plate 307 to shrink through reverse rotation, so that the lifting plate 307 and the lifting protrusion 3031 can stop the flipping operation. However, the slide bar 2042 slides in the supporting slot 2053, driving the fixed plate 204, the slide plate 202 and the support plate 201 to move in the opposite direction, and re-supporting the precast concrete panel 400 that has been flipped.
