Description

Technical Field

[0001] The invention relates to the technical field of vehicle frames, in particular to a combined snowplow vehicle frame. Background Art

[0002] The snowplow frame is the main supporting structure of the snowplow. It is similar to the frame of a car and plays the role of bearing and connecting other components. It carries many components such as the engine, gearbox, snow removal device, cab, various hydraulic systems, electrical systems, etc. The frame is usually composed of two longitudinal beams and several cross beams. Since the position of the cross beams is fixed, the supporting position of the longitudinal beams is too single. During the snow removal process, the snowplow may encounter various complex road conditions and snow conditions of different intensities. When the snow pusher encounters greater resistance, such as thick snow piles or hard objects hidden under the snow, the frame longitudinal beams will be subjected to greater impact force. Since the position of the cross beams is fixed, the impact force will be concentrated near the connection nodes between the cross beams and the longitudinal beams. These nodes are subjected to concentrated stress for a long time and are prone to fatigue cracks. Over time, the frame structure will be damaged. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, and this embodiment provides a combined snowplow frame. The combined snowplow frame includes a frame assembly 100, including a longitudinal beam 101, a fixed crossbeam 102 is fixed to the longitudinal beam 101 by bolts, and a movable crossbeam 103 is arranged on the longitudinal beam 101.

[0035] There are multiple fixed crossbeams 102 , which are evenly distributed in a straight line between the two longitudinal beams 101 . The fixed crossbeams 102 are used to stably connect the two longitudinal beams 101 . There are two movable crossbeams 103 , which are respectively located at the two ends of the inner sides of the two longitudinal beams 101 .

[0036] When the longitudinal beam 101 is subjected to an impact force, the dynamic cross beam 103 will move after the impact force ends, and its support point for the longitudinal beam 101 will also change accordingly. This helps to disperse the stress that may have been concentrated in certain parts of the longitudinal beam 101 to different areas. For example, when the snowplow frequently hits a snow pile or a bump on the road surface, the stress will be dynamically distributed on the longitudinal beam 101, avoiding the stress from being concentrated at a fixed point for a long time, thereby greatly reducing the risk of local fatigue damage and cracks on the longitudinal beam 101 and extending the service life of the frame longitudinal beam 101.

[0037] The movable cross beam 103 will not move until the impact force of the longitudinal beam 101 ends, thereby ensuring that the longitudinal beam 101 has sufficient stability when subjected to the impact force.

[0038] Specifically, the auxiliary component 200 is arranged on the longitudinal beam 101 and the movable cross beam 103, and includes a moving part 201. The moving part 201 includes a reciprocating roller 201a. The reciprocating roller 201a is inserted into the movable cross beam 103. A fixed shaft 201b is fixed in the movable cross beam 103, and the fixed shaft 201b is meshed with the reciprocating roller 201a. A support block 201c is fixed to the inner wall of the longitudinal beam 101, and the reciprocating roller 201a is connected to the support block 201c through a bearing.

[0039] There are two groups of auxiliary components 200 , corresponding to two movable beams 103 respectively. There are two groups of moving parts 201 on one movable beam 103 , which are respectively located on both sides of the movable beam 103 .

[0040] Pulleys are fixed at the ends of the two reciprocating rollers 201a, and the two pulleys are connected by belt transmission, so that when the reciprocating roller 201a on one side rotates, it can drive the other reciprocating roller 201a to rotate, and the support block 201c is used to support the reciprocating roller 201a.

[0041] When the reciprocating roller 201a rotates, it will drive the movable crossbeam 103 to move through the cooperation of the fixed shaft 201b, so that the movable crossbeam 103 can change the supporting point of the longitudinal beam 101, thereby avoiding the situation where stress is concentrated on a certain fixed point for a long time.

[0042] Specifically, the auxiliary component 200 further includes a trigger member 202, which includes a fixed sleeve 202a, which is fixed in the longitudinal beam 101, in which a sensing ball 202b is arranged, a plug hole 201a-1 is provided in the reciprocating roller 201a, a movable column 202c is inserted in the plug hole 201a-1, one end of the movable column 202c extends into the fixed sleeve 202a, and a connecting plate 202 is arranged at the end of the movable column 202c. d, the connecting plate 202d is fixed to the sensing ball 202b, a movable groove 201a-2 is opened in the reciprocating roller 201a, a positioning shaft 202e is movably connected in the movable groove 201a-2, a first spiral groove 202c-1 is opened on the movable column 202c, the positioning shaft 202e slides in the first spiral groove 202c-1, a fourth spring 202g is fixed to the inner wall of the fixed sleeve 202a, and one end of the fourth spring 202g is in contact with the sensing ball 202b.

[0043] The sensing ball 202b has a certain weight, and the fourth spring 202g is used to apply a thrust to the sensing ball 202b so that the sensing ball 202b will not move randomly.

[0044] When the snow pusher encounters greater resistance and causes the snowplow to vibrate, and the longitudinal beam 101 is subjected to impact force, the sensing ball 202b will be vibrated and move toward the front of the vehicle, driving the connecting plate 202d and the movable column 202c to move. At this time, the movable column 202c can rotate while moving. When the movable column 202c rotates, the positioning shaft 202e will not rotate, and the reciprocating roller 201a will not rotate.

[0045] When the snow pusher passes over a hard object, the fourth spring 202g will push the sensing ball 202b to move in the opposite direction, and drive the connecting plate 202d and the movable column 202c through the sensing ball 202b, so that the movable column 202c moves into the socket 201a-1. At this time, the movable column 202c will not rotate, and the positioning shaft 202e will rotate along the first spiral groove 202c-1, so that the positioning shaft 202e can drive the reciprocating roller 201a to rotate.

[0046] When the movable column 202c moves toward the outside of the socket 201a-1, it will drive the positioning shaft 202e to move horizontally through the first spiral groove 202c-1, and make the positioning shaft 202e contact the inner wall of the movable groove 201a-2. When the movable column 202c moves into the inside of the socket 201a-1, it will push the positioning shaft 202e to move horizontally again through the first spiral groove 202c-1, so that the positioning shaft 202e contacts the inner wall on the other side of the movable groove 201a-2. Only then will the positioning shaft 202e rotate along the first spiral groove 202c-1, so that the reciprocating roller 201a will not rotate in the initial stage of the movable column 202c moving into the socket 201a-1.

[0047] Example 2

[0048] Reference Figure 2-Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] Specifically, the auxiliary component 200 also includes a locking member 203, the locking member 203 includes a locking block 203a, a chamber 103-1 is opened in the movable cross beam 103, the locking block 203a is located in the chamber 103-1, a slot 101-1 is opened on the longitudinal beam 101, the locking block 203a is engaged with the slot 101-1, a first spring 203b is fixed to one side of the locking block 203a, and the other end of the first spring 203b is fixed to the inner wall of the chamber 103-1.

[0050] There are two groups of locking members 203 , which are respectively located at two sides of the chamber 103 - 1 . There are multiple slots 101 - 1 , which are evenly distributed on the longitudinal beam 101 in a straight line.

[0051] When the locking block 203a is engaged with the slot 101-1, the movable cross beam 103 can be locked through the cooperation of the two, so that when the longitudinal beam 101 is subjected to impact force, the stability of the movable cross beam 103 can be ensured, and the movable cross beam 103 can be prevented from moving when the longitudinal beam 101 is subjected to impact force, thereby reducing the bearing capacity of the longitudinal beam 101.

[0052] The first spring 203b is used to apply a thrust to the locking block 203a, so that the locking block 203a is more tightly engaged with the slot 101-1.

[0053] Specifically, the auxiliary component 200 also includes a connecting member 204, which includes a positioning sleeve 204a, which is fixed to one side of the connecting plate 202d, and the movable column 202c is rotatably connected to the positioning sleeve 204a through a bearing, a fixed frame 204b is fixed to one side of the positioning sleeve 204a, and a clamping block 204c is arranged in the fixed frame 204b, and a clamping slot 202c-2 is opened on the movable column 202c, and the clamping block 204c is engaged with the clamping slot 202c-2, and a second spring 204d is fixed to the top of the clamping block 204c, and the top of the second spring 204d is fixed to the inner wall of the fixed frame 204b.

[0054] The positioning sleeve 204a is used to connect the connecting plate 202d and the movable column 202c, so that when the connecting plate 202d moves, it can drive the movable column 202c to move.

[0055] One side of the block 204c is inclined, and the block 204c cooperates with the slot 202c-2 to limit the movable column 202c, so that the movable column 202c can rotate when it moves to the outside of the socket 201a-1, but cannot rotate when it moves to the inside of the socket 201a-1.

[0056] The second spring 204d is used to apply a thrust to the clamping block 204c, so that the clamping block 204c and the clamping slot 202c-2 are more tightly engaged.

[0057] Specifically, the auxiliary component 200 also includes a pulling member 205, which includes a rotating sleeve 205a, which is rotatably connected to the movable crossbeam 103, a connecting rod 205b is fixed to one side of the locking block 203a, a connecting rope 205c is fixed to one side of the connecting rod 205b, and the other end of the connecting rope 205c is fixed to the rotating sleeve 205a.

[0058] When the rotating sleeve 205a rotates, the connecting rope 205c is reeled up, and the connecting rod 205b and the locking block 203a are driven to move through the connecting rope 205c, so that the locking block 203a can be separated from the slot 101-1, and the movable beam 103 can be unlocked, so that the movable beam 103 can move.

[0059] The connecting rope 205c is elastic, and its elastic force is greater than that of the first spring 203b. When the locking block 203a is separated from the slot 101-1 and cannot move further, if the rotating sleeve 205a is still rotating, the connecting rope 205c will be stretched.

[0060] Specifically, a rotating column 205d is rotatably connected in the support block 201c, a sliding groove 205d-1 is provided on the rotating column 205d, a sliding block 205e is fixed in the rotating sleeve 205a, and the sliding block 205e slides in the sliding groove 205d-1.

[0061] The rotating column 205d is connected to the rotating sleeve 205a by the cooperation of the sliding groove 205d-1 and the sliding block 205e. When the rotating column 205d rotates, the rotating sleeve 205a can be driven to rotate.

[0062] Specifically, the auxiliary component 200 also includes a rotating member 207, which includes a connecting block 207a, which is fixed to one side of the connecting plate 202d, a connecting sleeve 207b is fixed to one side of the connecting block 207a, a movable sleeve 207c is rotatably connected to the connecting sleeve 207b, a connecting shaft 207d is fixed to the movable sleeve 207c, a second spiral groove 205d-2 is opened on the rotating column 205d, and the connecting shaft 207d slides in the second spiral groove 205d-2.

[0063] The connecting sleeve 207b is connected and fixed to the connecting plate 202d via the connecting block 207a. A through groove is provided on the fixing sleeve 202a, and the connecting block 207a slides in the through groove.

[0064] When the connecting plate 202d moves initially, it will drive the fixed sleeve 202a and the movable sleeve 207c to move. At this time, the movable sleeve 207c can rotate, so that the connecting shaft 207d will move along the inner wall of the second spiral groove 205d-2, so that the rotating column 205d will not rotate.

[0065] When the connecting plate 202d drives the movable sleeve 207c to move in the opposite direction, the movable sleeve 207c will not rotate, so the connecting shaft 207d and the second spiral groove 205d-2 can be used to drive the rotating column 205d to rotate, so that the rotating sleeve 205a can be driven to rotate through the rotating column 205d.

[0066] Example 3

[0067] Reference Figure 1-Figure 10 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0068] Specifically, a support frame 207e is fixed on one side of the connecting sleeve 207b, a limiting block 207f is arranged in the support frame 207e, a limiting groove 207c-1 is opened on the movable sleeve 207c, the limiting block 207f is engaged with the limiting groove 207c-1, a third spring 207g is fixed on the top of the limiting block 207f, and the top of the third spring 207g is fixed to the inner wall of the support frame 207e, an extrusion rod 207h is fixed on one side of the support block 201c, and a force groove 207f-1 is opened on the limiting block 207f.

[0069] The cooperation between the limiting block 207f and the limiting groove 207c-1 is used to limit the movable sleeve 207c, so that the movable sleeve 207c can rotate during the initial movement, and will not rotate when the movable sleeve 207c moves in the reverse direction and resets.

[0070] The inner wall of the force groove 207f-1 is inclined. When the movable sleeve 207c is in the initial position, the extrusion rod 207h will squeeze the inclined surface of the inner wall of the force groove 207f-1, and through the cooperation of the two, the limit block 207f will move upward and separate from the limit groove 207c-1, thereby releasing the restriction on the movable sleeve 207c, allowing the movable sleeve 207c to rotate in any direction, and then allowing the rotating sleeve 205a to unwind the connecting rope 205c and enable the locking block 203a to engage with the slot 101-1 again.

[0071] Specifically, a positioning column 202f is fixed in the movable groove 201a-2, and the positioning shaft 202e is movably connected to the outer side of the positioning column 202f.

[0072] The positioning column 202f is used to position the positioning shaft 202e.

[0073] Specifically, one side of the clamping block 204c is inclined, and there are multiple clamping slots 202c-2, which are evenly distributed in a ring shape on the outer side of the movable column 202c.

[0074] Specifically, there are multiple limiting grooves 207c-1, which are evenly distributed in a ring shape on the outside of the moving sleeve 207c, and one side of the limiting block 207f is inclined.

[0075] During use, when the snow pusher encounters greater resistance and causes the snowplow to vibrate, and the longitudinal beam 101 is subjected to impact force, the sensing ball 202b will move toward the front of the vehicle due to the vibration, and drive the connecting plate 202d and the movable column 202c to move. At this time, the movable column 202c can rotate while moving. When the movable column 202c rotates, the positioning shaft 202e will not rotate, and the reciprocating roller 201a will not rotate, so that the movable cross beam 103 will not move, thereby ensuring that the longitudinal beam 101 has sufficient stability when subjected to impact force.

[0076] At the same time, when the connecting plate 202d moves initially, it will drive the fixed sleeve 202a and the movable sleeve 207c to move. At this time, the movable sleeve 207c can rotate, so that the connecting shaft 207d will move along the inner wall of the second spiral groove 205d-2, so that the rotating column 205d will not rotate.

[0077] When the snow pusher passes over a hard object, the fourth spring 202g will push the sensing ball 202b and the connecting plate 202d to move in the opposite direction, and drive the movable sleeve 207c to move in the opposite direction through the connecting plate 202d. At this time, the movable sleeve 207c will not rotate, so that the rotating column 205d can be driven to rotate through the cooperation between the connecting shaft 207d and the second spiral groove 205d-2, and the rotating sleeve 205a can be driven to rotate through the rotating column 205d.

[0078] When the rotating sleeve 205a rotates, the connecting rope 205c is reeled up, and the connecting rod 205b and the locking block 203a are driven to move through the connecting rope 205c, so that the locking block 203a can be separated from the slot 101-1, and the movable beam 103 can be unlocked, so that the movable beam 103 can move.

[0079] When the connecting plate 202d moves in the reverse direction, it will drive the movable column 202c to move, so that the movable column 202c moves into the socket 201a-1. At this time, the movable column 202c will not rotate, and the positioning shaft 202e will rotate along the first spiral groove 202c-1, so that the positioning shaft 202e can drive the reciprocating roller 201a to rotate. When the reciprocating roller 201a rotates, it will drive the movable crossbeam 103 to move through the cooperation of the fixed shaft 201b, and its support point on the longitudinal beam 101 will also change accordingly, which helps to disperse the stress that may have been concentrated in certain parts of the longitudinal beam 101 to different areas. For example, when the snow pusher frequently hits the snow pile or road protrusions, the stress will be dynamically distributed on the longitudinal beam 101, avoiding the stress from being concentrated on a fixed point for a long time, thereby greatly reducing the risk of local fatigue damage and cracks on the longitudinal beam 101 and extending the service life of the frame longitudinal beam 101.

[0080] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
