Description

Technical Field

[0001] This invention relates to the field of screw presses, and more particularly to a connection system between the body beam and the support arm of a double-disc friction screw press. Background Technology

[0002] Friction screw press refers to a composite molding equipment composed of hydraulic and friction transmission mechanisms. The machine is divided into two stages of pressurization. First, a hydraulic cylinder is used for pre-pressurization, and then a flywheel screw is used for high pressure. This combines the characteristics of hydraulic and friction brick presses, which can more effectively improve the quality of brick pressing. The friction screw press is based on the structure of a large screw press with the addition of a pre-pressurization cylinder pressurization device.

[0003] The double-disc friction screw press is a molding equipment that uses friction drive to press refractory bricks by impact pressure.

[0004] In existing double-disc friction screw presses, the connection between the machine body beam and the left and right support arms is mostly achieved by bolts. The bolts fix the support arms to the beam, and the bolts bear the main weight of the support arms. Since friction discs are installed on the support arms, the bolts are prone to loosening or even breaking, which affects the normal use of the equipment. Therefore, providing a connection structure that makes the connection between the support arms and the beam more stable is an urgent problem to be solved. Summary of the Invention

[0005] To make the connection between the support arm and the machine body beam more stable, the present invention provides a connection system between the machine body beam and the support arm of a double-disc friction screw press.

[0006] The present invention provides a connection system between the body crossbeam and the support arm of a double-disc friction screw press, which adopts the following technical solution:

[0007] A body beam and support arm connection system for a double-disc friction screw press includes a side connection mechanism disposed on both sides of the symmetrically arranged support arm and a top fixing mechanism disposed on the top of the support arm. The bottom of the support arm is provided with a support mechanism that abuts against and supports the bottom of the support arm. The side connection mechanism includes a support rod. Multiple identical connection slots are symmetrically opened on both sides of the support arm. A connecting block corresponding to each connection slot is fixed on the side of the support rod near the support arm. The connecting block is inserted into the connection slot. Bolts for fixing the support rod and the crossbeam are threaded onto the support rod.

[0008] By adopting the above technical solution, the connecting block is inserted into the connecting groove, and the bolts fix the connecting rod and the crossbeam, thereby fixing the two sides of the support arm and the crossbeam. The top fixing mechanism fixes the top of the support arm to the crossbeam, and the support mechanism abuts against the bottom of the support arm to share the weight of the support arm. The support arm is fixed and supported from the top, side wall and bottom of the support arm, thereby making the connection between the support arm and the crossbeam more stable.

[0009] Optionally, the top and bottom of the connecting groove are provided with limiting groove step groove one and step groove two, and the top and bottom of the connecting block are respectively fixed with protrusion one and protrusion two, protrusion one is inserted into step groove one, and protrusion two is inserted into step groove two.

[0010] By adopting the above technical solution, on the one hand, protrusion one and protrusion two can increase the contact area between the support arm and the support rod, and increase the firmness of the connection between the support arm and the support rod. On the other hand, protrusion one and protrusion two are respectively inserted into step groove one and step groove two, so that the support arm will not have vertical and horizontal displacement, and increase the stability of the connection.

[0011] Optionally, the top fixing mechanism includes a positioning plate welded to the top of the support arm. The positioning plate extends downward from the top of the support arm. A connecting plate is fixed at the bottom of the positioning plate near the crossbeam. The connection between the connecting plate and the positioning plate is a stepped groove, which is used for the connecting plate to engage.

[0012] By adopting the above technical solution, the slot and the stepped slot 11 are matched to make the contact between the connecting plate and the crossbeam tighter. The connecting plate is threaded with bolts, which fix the top of the connecting plate and the crossbeam, thereby fixing the positioning plate and the support arm to the crossbeam.

[0013] Optionally, a fixing plate is fixed to the top of the positioning plate, and the fixing plate abuts against the side of the support arm away from the crossbeam to hook the top of the support arm.

[0014] By adopting the above technical solution, the fixing plate applies a tensile force to the support arm, making the connection between the support arm and the crossbeam more stable.

[0015] Optionally, the support mechanism includes a support plate disposed on the crossbeam, and multiple sets of support components are disposed at the bottom of the support plate, forming a triangle between the support components, the crossbeam, and the support plate.

[0016] By adopting the above technical solution, the support plate abuts against the bottom of the support arm, which can share the weight of the support arm, reduce the stress points of the support arm, support rod and positioning plate, and form a triangle between the support component, the crossbeam and the support plate. According to the stability of the triangle, the connection between the support plate and the crossbeam is more stable, which in turn makes the connection point between the support arm and the crossbeam more stable.

[0017] Optionally, the bottom of the support plate is provided with a storage groove, and the support assembly includes a connecting rod disposed in the storage groove. A T-shaped slider is hinged to the end of the connecting rod away from the crossbeam. A T-shaped groove is provided on one side of the support plate located in the storage groove. The T-shaped slider is slidably connected in the T-shaped groove. A vertically arranged guide groove is provided on the side wall of the crossbeam corresponding to the position of the storage groove. A guide block is provided at the end of the connecting rod away from the slider. The guide block can detach from the storage groove and slide downward into the guide groove. A positioning assembly for fixing the connecting rod is provided on the side of the support plate away from the crossbeam.

[0018] By adopting the above technical solution, the guide block can detach from the storage groove and slide downward into the guide groove, so that a triangle is formed between the connecting rod, the support plate and the crossbeam. The positioning component fixes the connecting rod. According to the stability of the triangle, the connecting rod can strengthen the support of the support plate, share the weight of the support plate, and make the support plate support the arm more stable.

[0019] Optionally, a limiting groove is provided on the side of the connecting rod near the support plate. A reinforcing rod is housed in the limiting groove. One end of the reinforcing rod is slidably connected to the limiting groove and can rotate within the limiting groove, while the other end is hinged to the bottom of the support plate.

[0020] By adopting the above technical solution, a triangle is formed between the reinforcing rod, the connecting rod, and the support plate, and a triangle is formed between the connecting rod, the reinforcing rod, and the crossbeam. The reinforcing rod can enhance the stability of the connecting rod and make the connecting rod more robust.

[0021] Optionally, the positioning component includes a positioning rod disposed at the end of the support plate away from the crossbeam, a stop block fixedly disposed at the position of the positioning rod corresponding to the storage groove, a limiting block fixedly disposed on the stop block, the stop block being inserted into the storage groove, the limiting block on the stop block being inserted into the T-shaped sliding groove, and a bolt threaded on the stop block to fix the positioning block and the support plate.

[0022] By adopting the above technical solution, the stop block can be inserted into the storage groove, and the limiting block on the stop block can be inserted into the T-shaped sliding groove. The stop block will block the T-shaped slider, thereby fixing the connecting rod.

[0023] Optionally, a receiving groove is provided on the side of the crossbeam near the support arm, and a support plate is slidably connected in the receiving groove. A limiting plate is fixed at the end of the support plate away from the open end of the receiving groove, and the size of the limiting plate is larger than the position of the open end of the receiving groove.

Figure 1A connection system between the body beam and the support arm of a double-disc friction screw press includes side connection mechanisms 3 symmetrically arranged on both sides of the support arm 2, and a top fixing mechanism 4 disposed on the top of the support arm 2. A support mechanism 5 is disposed on the bottom of the support arm 2 corresponding to the crossbeam 1. The side connection mechanisms 3 and the top fixing mechanism 4 fix the support arm 2 to the crossbeam 1. The support mechanism 5 abuts against and supports the bottom of the support arm 2, which can share the weight of the support arm 2, thereby making the connection between the support arm 2 and the crossbeam 1 more stable.

[0038] Reference Figure 2 The top fixing mechanism 4 includes a positioning plate 41 abutting against the top of the support arm 2. The positioning plate 41 is welded to the top of the support arm 2 and extends downward from the top of the support arm 2. A fixing plate 42 is fixedly provided on the top of the positioning plate 41. The fixing plate 42 abuts against the side of the support arm 2 away from the crossbeam 1 to hook the top of the support arm 2. A connecting plate 43 is fixedly provided at the bottom of the positioning plate 41 near the crossbeam 1. The connection between the connecting plate 43 and the positioning plate 41 is a stepped groove. A stepped groove 11 is provided on the crossbeam 1 near the top of the support arm 2. The stepped groove 11 is used for the connecting plate 43 to be engaged. The groove and the stepped groove 11 are fitted together to make the contact between the connecting plate 43 and the crossbeam 1 tighter. Bolts are threaded on the connecting plate 43. The bolts fix the connecting plate 43 and the top of the crossbeam 1, thereby fixing the positioning plate 41 and the support arm 2 to the crossbeam 1.

[0039] Reference Figure 3 and Figure 4 The side connection mechanism 3 includes a support rod 31. Multiple identical connection slots 21 are symmetrically provided on both sides of the contact surface between the support arm 2 and the crossbeam 1. The connection slots 21 are evenly spaced along the vertical direction of the support arm 2. Stepped slots 11-1 and 11-2 are provided at the top and bottom of the connection slots 21, forming half of a cross shape. A connecting block 32 corresponding to each connection slot 21-1 is fixed to the side of the support rod 31 near the support arm 2. The connecting block 32 is inserted into the connection slot 21. A protrusion 321 and a protrusion 322 are fixed to the top and bottom of the connecting block 32, respectively. Block 1 321 is inserted into step groove 11-1, and protrusion 2 322 is inserted into step groove 11-2. On the one hand, protrusion 1 321 and protrusion 2 322 can increase the contact area between the support arm 2 and the support rod 31, and increase the firmness of the connection between the support arm 2 and the support rod 31.

According to the stability of the triangle, the connecting rod 531 can strengthen the support of the support plate 51, share the weight of the support plate 51, and make the support plate 51 support the support arm 2 more stably.

[0042] A limiting groove 534 is provided on the side of the connecting rod 531 near the support plate 51. A reinforcing rod 535 is housed in the limiting groove 534. One end of the reinforcing rod 535 is slidably connected to the limiting groove 534 and can rotate within the limiting groove 534. The other end is hinged to the bottom of the support plate 51. A triangle is formed between the reinforcing rod 535, the connecting rod 531 and the support plate 51. A triangle is also formed between the connecting rod 531, the reinforcing rod 535 and the crossbeam 1. The reinforcing rod 535 can enhance the stability of the connecting rod 531 and make the connecting rod 531 more robust.

[0046] Finally, slide the support plate 51 outward from the receiving groove 12 so that the support plate 51 abuts against the bottom of the support arm 2. Slide the connecting rod 531 downward until the guide block 533 slides to the bottom of the guide groove 13, so that the connecting rod 531, the crossbeam 1 and the support plate 51 form a triangle. Then, the limiting block 542 on the stop block 541 on the positioning rod 54 can be inserted into the T-shaped slide groove 513. The stop block 541 blocks the T-shaped slider 532, thereby fixing the connecting rod 531. At the same time, rotate the positioning strip 521 so that the positioning strip 521 abuts against the stop strip 52.
