[0002] In the material transportation production line, the role of the support device is to enable the material transportation equipment to transport materials smoothly. The support device includes diagonal braces, crossbeams and pillars. The support devices currently used in material transportation equipment are mostly non-standard designs with poor versatility. They cannot flexibly adjust the angles between the diagonal braces and crossbeams, and between the diagonal braces and pillars, and are difficult to adapt to different installation requirements. Even if a small number of support devices can achieve angle adjustment between the diagonal braces and crossbeams, and between the diagonal braces and pillars, their technical solutions are too complicated, resulting in a narrow scope of application and high cost of the support devices, and are still difficult to adapt to different installation requirements. Therefore, a new type of support device is needed to overcome the limitations of the prior art, improve the versatility of the support device, and broaden the scope of application of the support device.

A supporting device for supporting material transport equipment in a sand and gravel production line, characterized in that: The supporting device comprises: A crossbeam assembly, the crossbeam assembly comprising a transversely arranged crossbeam and a crossbeam fixing seat for connecting with the material transport equipment, the crossbeam fixing seat being detachably mounted on the crossbeam; A support assembly, the support assembly comprising a vertically arranged support and a support fixing seat, the support fixing seat being detachably mounted on the support; and A diagonal brace assembly is detachably connected between the crossbeam and the pillar, and the diagonal brace assembly includes a first support rod, a second support rod and a telescopic mechanism connected between the first support rod and the second support rod, one end of the first support rod is pivotally mounted on the crossbeam fixing seat, and the other end of the first support rod is detachably connected to the telescopic mechanism; one end of the second support rod is pivotally mounted on the pillar fixing seat, and the other end of the second support rod is detachably connected to the telescopic mechanism; the telescopic mechanism is used to adjust its own length by telescoping, thereby adjusting the distance between the ends of the first support rod and the second support rod connected to the telescopic mechanism.

2. The support device according to claim 1, characterized in that: The telescopic mechanism comprises a sleeve, a telescopic rod and a locking nut. The telescopic rod is telescopically sleeved in the sleeve. The locking nut is sleeved on the telescopic rod and limits the position of the telescopic rod relative to the sleeve by abutting against the sleeve.

3. The supporting device according to claim 2, characterized in that: The sleeve is provided with at least one operating hole penetrating through the tube wall of the sleeve, and the length direction of the operating hole is consistent with the axial direction of the sleeve.

4. The supporting device according to claim 1, characterized in that: The diagonal brace assembly includes a first pivot mechanism, which is installed between the beam fixing seat and the first support rod. The first pivot mechanism includes a first adjustment plate vertically fixed to the beam fixing seat, a second adjustment plate fixedly connected to the first support rod near one end of the beam, and a first pin shaft. The first adjustment plate has a first adjustment hole, the second adjustment plate has a second adjustment hole, and the first pin shaft passes through the first adjustment hole and the second adjustment hole.

5. The supporting device according to claim 4, characterized in that: The diagonal brace assembly includes a first connecting mechanism, which is installed between the first pivot mechanism and the first support rod. The first connecting mechanism includes a first connecting member, a second connecting member and a first pre-tightening bolt. The first connecting member is provided with a first screw hole, and the second connecting member is provided with a second screw hole. The first pre-tightening bolt passes through the first screw hole and the second screw hole to adjust the gap between the first connecting member and the second connecting member, thereby providing a pre-tightening force for the first support rod.

6. The supporting device according to claim 5, characterized in that: The first connecting mechanism also includes a first gasket, which is provided with a notch aligned with the first pre-tightening bolt, and the first gasket is inserted between the first connecting member and the second connecting member to fill the gap between the first connecting member and the second connecting member.

7. The supporting device according to claim 1, characterized in that: The diagonal brace assembly also includes a second pivot mechanism, which is installed between the pillar fixing seat and the second support rod. The second pivot mechanism includes a third adjustment plate vertically fixed to the pillar fixing seat, a fourth adjustment plate fixedly connected to the second support rod and a second pin shaft, the third adjustment plate has a third adjustment hole, the fourth adjustment plate has a fourth adjustment hole, and the second pin shaft passes through the third adjustment hole and the fourth adjustment hole.

8. The supporting device according to claim 7, characterized in that: The diagonal brace assembly also includes a second connecting mechanism, which is installed between the second pivot mechanism and the second support rod. The second connecting mechanism includes a third connecting member, a fourth connecting member and a second pre-tightening bolt. The third connecting member has a third screw hole, and the fourth connecting member has a fourth screw hole. The second pre-tightening bolt passes through the third screw hole and the fourth screw hole to adjust the gap between the third connecting member and the fourth connecting member, thereby providing a pre-tightening force for the second support rod.

9. The supporting device according to claim 8, characterized in that: The second connecting mechanism also includes a second gasket, which is provided with a recess aligned with the second pre-tightening bolt, and the second gasket is inserted between the third connecting member and the fourth connecting member to fill the gap between the third connecting member and the fourth connecting member.

10. The supporting device according to claim 1, characterized in that: The support column assembly also includes an abutment plate and a tightening bolt. The abutment plate is installed on the side of the support column and is provided with a fifth screw hole. The tightening bolt passes through the fifth screw hole and abuts against the support column fixing seat.
