[0001] The invention relates to the technical field of mechanical hoisting, and in particular to a mechanical installation and hoisting device for stone crushing used in road construction. Background Art

[0002] Stone crushing machinery is a commonly used equipment in road construction. It is usually used to crush large stones into particles of required sizes to meet the needs of different projects. The installation of stone crushing machinery requires lifting equipment. Existing lifting equipment is usually a single overhead crane, crane, etc. This type of lifting equipment cannot change the placement of mechanical parts. That is, when individual mechanical parts with eccentric center of gravity are placed on the ground, the mechanical parts are in an inclined state due to their shape (that is, two or more lifting ears are not on the same horizontal plane). However, when the crushing machinery is installed, the mechanical parts need to be level so that the mechanical parts can be correctly connected. That is, the existing lifting equipment cannot meet the requirements of crushing machinery installation, and the staff can only rely on additional tools to change the state of the mechanical parts. As a result, the installation efficiency of the crushing machinery is low, and the work intensity and danger of the staff are high. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: set, connected, connected should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-Figure 5 As shown in the figure, it is an embodiment of the present invention, which proposes a stone crushing machine installation hoisting equipment for road construction, which is used for stably and efficiently installing the crushing machine to solve the problem that the mechanical parts of the existing hoisting equipment are tilted during the hoisting process, thereby affecting the normal installation. The equipment includes: a crossbeam 1; no less than two first wheels 2, both rotatably connected to the crossbeam 1; a second wheel 3, which is rotatable on the crossbeam 1; a load-bearing chain 4, which is wound around the upper side of the first wheel 2 and the second wheel 3; hooks 5, the number of which is the same as the number of the first wheels 2, which are respectively arranged at the ends of the load-bearing chain 4; a connecting mechanism, which is arranged on the crossbeam 1 and is used to connect with external hoisting equipment; a balancing mechanism, It is arranged on the crossbeam 1, and is used to make the first wheel 2 and the crossbeam 1 rotate relative to each other, so as to ensure that the lengths of the hanging load-bearing chains 4 on different first wheels 2 are the same; the locking mechanism, the number of which is the same as the number of the first wheels 2, is arranged on the crossbeam 1, and is used to change the relative connection relationship between the first wheel 2 and the crossbeam 1, and the connection mechanism includes: a first sliding member 602, fixedly connected to the crossbeam 1; a connecting member 601, spline-connected to the first sliding member 602; a steel rope 603, one end of which is fixedly connected to the connecting member 601, and the other end of which is connected to an external lifting device, and a first elastic element 604 is fixedly connected between the connecting member 601 and the first sliding member 602.

[0025] In the above scheme, the crossbeam 1 is made of high-strength steel, the purpose of which is to provide stable support for the hoisting work. Multiple first wheels 2 are symmetrically distributed on the crossbeam 1, and the hanging lengths of the load-bearing chains 4 on different first wheels 2 are consistent, so that the mechanical parts are horizontally hoisted. The hoisting equipment includes but is not limited to a bridge crane (not shown in the schematic diagram). The first elastic element 604 is a spring, which is used to reset the first sliding member 602. When the present invention is used to hoist the crushing machine, the hook 5 is first set on the lifting ear of the mechanical part, and then the bridge crane is used to move the steel rope 603 upward, and the upward movement of 603 drives the connecting member 601 to move upward together. The connecting member 601 and the first sliding member 602 slide relative to each other, and the first elastic element 604 is compressed. After the connecting member 601 and the first sliding member 602 slide to the limit position, the connecting member 601 drives the first sliding member 602 to move upward together, and the first sliding member 602 drives the crossbeam 1 and the parts thereon to move upward together, and the mechanical parts are hoisted to the installation position. During the process, the load-bearing chain 4 located in the horizontal area is moved left and right through the rotation of the second wheel 3, so as to adjust the height of different hooks 5, so as to make the mechanical parts in a horizontal state, so as to prevent the mechanical parts in a tilted state from being difficult to position during subsequent installation, thereby reducing work efficiency.

[0026] like Figure 1-Figure 4 As shown, the balancing mechanism includes: a limit frame 701, slidably connected to the beam 1; a first limit column 702, the number of which is the same as the number of the first wheel 2, both of which are arranged on the limit frame 701; a second limit column 703, which is arranged on the limit frame 701; a limit plate 704, fixedly connected to the second wheel 3, the limit plate 704 is provided with a first limit groove 705, the first limit groove 705 is limited and cooperated with the second limit column 703; a first limit block 706, fixedly connected to the connecting member 601.

[0027] In the above scheme, the first limiting block 706 is an isosceles triangle, which is used to squeeze the adjacent first limiting columns 702 respectively. Before lifting, if the mechanical parts are placed obliquely on the ground due to their shape (that is, two or more lifting ears are not on the same horizontal plane, and two lifting ears are taken as an example), the staff will pull down the load-bearing chain 4 on one of the first wheels 2 (for ease of understanding, take pulling the load-bearing chain 4 on the left first wheel 2 as an example), and the moving load-bearing chain 4 drives the first wheel 2 and the second wheel 3 to rotate, and the second wheel 3 drives the limiting plate 704 to deflect counterclockwise, and the first limiting groove 705 begins to squeeze the second limiting column 703 to the left, and the second limiting column 703 drives the limiting frame 701 to move left together. In the process of the connecting member 601 moving upward, the connecting member 601 drives the first The limit block 706 moves upward together. After the first limit block 706 moves upward to contact the first limit column 702 on the right, as the first limit block 706 continues to move upward, the first limit block 706 squeezes the first limit column 702 on the right to the right, and the first limit column 702 (the second limit column 703) starts to move to the right, and the second limit column 703 squeezes the first limit groove 705 to the right. The limit plate 704 drives the second wheel 3 to deflect (reset) clockwise, so that the hanging lengths of the load-bearing chains 4 on different first wheels 2 are equal again, that is, the mechanical parts area is in a horizontal state, so as to prevent installation difficulties caused by the tilt of the mechanical parts during the lifting process, resulting in low installation efficiency, and if the machine in a tilted state is forcibly installed, it is easy to cause damage to the mechanical parts.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the locking mechanism includes: a second limit block 801, which is slidably connected to the beam 1, a second elastic element 802 is fixedly connected between the second limit block 801 and the beam 1, the first wheel 2 is provided with circumferentially distributed grooves 803 that cooperate with the second limit block 801; a transmission assembly, which is arranged on the beam 1, and is used to make the second limit block 801 and the beam 1 slide relative to each other.

[0029] In the above scheme, the second limit blocks 801 are multiple and evenly arranged, and are used to limit the first wheel 2 at multiple points, so as to improve the stability of the first wheel 2. The second elastic element 802 is a tension spring, and is used to reset the second limit block 801. After the mechanical parts are leveled, the second limit block 801 enters the groove 803 and limits the first wheel 2, so as to ensure the stability between the first wheel 2 and the beam 1 during the lifting process.

[0030] like Figure 2 and Figure 5As shown, the transmission assembly includes: a first extrusion member 901, which is slidably connected to the beam 1, the beam 1 is provided with a first channel 902 and a cavity 903, the first channel 902 and the cavity 903 are both filled with a transmission medium, the second limit block 801 is located in the cavity 903, the first extrusion member 901 seals and slides in the first channel 902, and the first extrusion member 901 is provided with a second limit groove 904; a limit rod 905, which is fixedly connected to the first limit block 706, and the limit rod 905 is limitedly matched with the second limit groove 904; the second limit groove 904 is composed of a vertical groove and an inclined groove connected to each other, and is used to make the first extrusion member 901 and the beam 1 slide relative to each other.

[0031] In the above scheme, the transmission medium in the first channel 902 and the cavity 903 is hydraulic oil. The inclined groove in the second limiting groove 904 is located on the upper side of the vertical groove, which is used to enable the second limiting block 801 to limit the first wheel 2 after the mechanical parts are leveled, so as to ensure that the first wheel 2 does not rotate relative to the crossbeam 1 during the lifting process. The length of the first limiting block 706 in the vertical direction is greater than the length of the projection of the second limiting groove 904 in the vertical direction, which is used to enable the second limiting block 801 to limit the adjacent first wheel 2 at the end of the leveling mechanical action. In the process of the first limiting block 706 moving upward, the first limiting block 706 drives the limiting rod 905 to move upward together, and the limiting rod 905 begins to slide upward along the vertical groove on the second limiting groove 904 (the mechanical parts gradually move upward during the process). After the mechanical parts are leveled, the limit rod 905 enters the inclined groove on the second limit groove 904. As the limit rod 905 continues to move upward, the limit rod 905 begins to squeeze the second limit groove 904, and the first extrusion piece 901 on the left begins to move to the left and squeezes the hydraulic oil in the first channel 902. Then the squeezed hydraulic oil enters the cavity 903, and the hydraulic oil in the cavity 903 squeezes the adjacent second limit block 801. The second limit block 801 slides relative to the beam 1, and the adjacent second elastic element 802 is stretched until the second limit block 801 enters the adjacent groove 803, thereby limiting the first wheel 2 and keeping the first wheel 2 and the beam 1 relatively still, thereby ensuring the stability of the mechanical parts during the lifting process and improving the lifting quality.

[0032] like Figure 1 , Figure 6 and Figure 7 As shown, the hook 5 includes: a second sliding member 1001, installed on the end of the load-bearing chain 4; a U-shaped member 1002, slidably connected to the second sliding member 1001; a stop rod 1003, rotatably connected to the U-shaped member 1002, and a third elastic element 1004 is fixedly connected between the U-shaped member 1002 and the stop rod 1003.

[0033] In the above scheme, the third elastic element 1004 is a torsion spring, which is used to reset the adjacent baffle rod 1003. Before hoisting the mechanical parts, the staff deflects the baffle rod 1003 upward, and the baffle rod 1003 and the U-shaped part 1002 rotate relative to each other, and the adjacent third elastic element 1004 is deformed. The U-shaped part 1002 is then passed through the lifting ear on the mechanical part, and then the baffle rod 1003 is released, which is reset under the action of the torque of the adjacent third elastic element 1004. In this way, the mechanical parts are suspended by a "closed loop" composed of the U-shaped part 1002 and the baffle rod 1003, thereby preventing the traditional open hook from accidentally detaching from the mechanical parts during the hoisting process, and even threatening the life safety of the staff.

[0034] like Figure 6 and Figure 7 As shown, it also includes: a stopper 1101, the number of which is the same as the number of U-shaped parts 1002, which is slidably connected to the U-shaped part 1002, the stopper 1101 and the stop rod 1003 are limited and matched, and an arc surface is provided on the upper part of the stopper 1101 for relative sliding with the adjacent U-shaped part 1002, and a fourth elastic element 1102 is fixedly connected between the stopper 1101 and the U-shaped part 1002.

[0035] In the above solution, the arc surface of the stopper 1101 gradually bends downward from left to right (with Figure 6 As shown in the figure, it is used to make it slide relative to the U-shaped piece 1002 when it is pressed downward by the blocking rod 1003. The transmission medium in the second channel 1202 is hydraulic oil. The fourth elastic element 1102 is a spring, which is used to reset the adjacent block 1101. Before deflecting the blocking rod 1003 upward, the staff moves the block 1101 to the left (with Figure 6 As shown), the fourth elastic element 1102 is compressed, and the block 1101 loses its limit on the baffle rod 1003, and then deflects the baffle rod 1003 upward, and then passes the baffle rod 1003 through the lifting ear on the mechanical part, and the staff releases the block 1101, and the block 1101 is reset under the action of the elastic force of the fourth elastic element 1102, and then in the process of resetting the baffle rod 1003, after the baffle rod 1003 contacts the arc surface on the block 1101, the block 1101 is squeezed and begins to move to the left, and the fourth elastic element 1102 is compressed again. When the baffle rod 1003 is reset and passes through the block 1101, the block 1101 is reset again and limits the baffle rod 1003, so as to prevent the baffle rod 1003 and the U-shaped member 1002 from rotating relative to each other due to factors such as vibration during the lifting process, thereby losing support for the mechanical parts, damaging the parts, and causing serious injuries to the staff.

[0036] like Figure 6 and Figure 7As shown, it also includes: second extrusion members 1201, the number of which is the same as the number of U-shaped members 1002, fixedly connected to the second sliding member 1001, the U-shaped member 1002 is provided with a second channel 1202, and the second channel 1202 is filled with a transmission medium; moving members 1203, the number of which is the same as the number of U-shaped members 1002, slidingly connected to the U-shaped member 1002, the moving member 1203 is fixedly connected to the stopper 1101, and the moving member 1203 is located in the second channel 1202.

[0037] In the above scheme, during the upward movement of the load-bearing chain 4, the load-bearing chain 4 drives the second sliding member 1001 to move upward together, and the second sliding member 1001 drives the adjacent second extruding member 1201 to move upward together. Since the blocking rod 1003 is blocked by the mechanical parts, the second sliding member 1001 slides relative to the adjacent U-shaped member 1002, and the second extruding member 1201 squeezes the hydraulic oil in the adjacent second channel 1202, and the hydraulic oil in the second channel 1202 squeezes the adjacent moving member 1203, and the moving member 1203 starts to move rightward (with Figure 6 Taking the example shown in the figure), the movable member 1203 drives the adjacent stop block 1101 to move to the right together, and the adjacent fourth elastic element 1102 is stretched. The stop block 1101 is used to limit the adjacent stop rod 1003, so that the stop rod 1003 and the U-shaped member 1002 remain relatively still, preventing the stop rod 1003 and the U-shaped member 1002 from moving relative to each other due to shaking during the lifting process, which may cause the mechanical parts to fall and pose a threat to the life safety of the staff.

[0038] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
