Description
Technical Field
The utility model relates to a slush pump technical field especially relates to a baffle mounting structure for slush pump.
Background
A mud pump is a machine that delivers a flushing fluid, such as mud or water, into a borehole during drilling. The conventional slurry pump is of a piston type or a plunger type, a power machine drives a crankshaft of the pump to rotate, and the crankshaft drives the piston or the plunger to reciprocate in a pump cylinder through a crosshead.
The guide plate is one of the key parts of the plunger pump, the guide plate has the function of enabling the crosshead to reciprocate on the guide plate, the guide plate is not only subjected to pressure from the crosshead, but also ensures the centering property of the crosshead during reciprocating motion, and therefore the guide plate is required to be firmly fixed with the support plate on the machine frame. The most common bolt fixing is currently performed, and the specific structure is as shown in fig. 2, wherein a pressing bolt 4 vertically penetrates through the support rib 2 from the guide plate 3 and is in threaded fit with a fastening plate 5 arranged in advance in the support rib 2, so as to realize locking. However, the mounting mode has defects, because the crosshead applies force in the vertical direction to the guide plate in the sliding process of the crosshead along the guide plate when the slurry pump is in a working state, the crosshead is easy to loosen after being used for a long time, so that the guide plate is unstable in fixation, the bearing capacity of the whole structure is influenced, and the service life is shortened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a baffle mounting structure for slush pump to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a guide plate mounting structure for a slurry pump comprises a support plate, a support rib arranged on the support plate and a guide plate fixed on the support rib, wherein the guide plate is arc-shaped, and an arc-shaped groove matched with the guide plate is formed in the support rib; the guide plate and the support ribs are fixed through compression bolts, and the installation direction of the compression bolts is perpendicular to the tangent plane direction of the guide plate.
The number of the compression bolts is at least two, and the two compression bolts are respectively arranged on two sides of the central axis of the guide plate and symmetrically distributed along the central axis.
An included angle formed between the two compression bolts is 60 degrees.
The pressing bolt comprises a large head part and a screw rod part with external threads, a countersunk hole used for clamping the large head part is formed in the guide plate, and a threaded hole matched with the screw rod part is formed in the supporting rib.
The utility model has the advantages that: the installation direction of the pressing bolt is perpendicular to the tangent plane of the arc-shaped guide plate, so that the laminating firmness strength of the contact surface of the guide plate and the supporting rib is increased, the pressing bolt is arranged on two sides of the central axis of the guide plate, the stress distribution is more uniform, the impact bearing capacity of the structure is increased, and the service life is prolonged. Compared with the existing installation mode, the installation method does not need to additionally arrange a fastening hole and a fastening plate in the supporting rib, and is more convenient to process.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of a mounting structure of a guide plate in the prior art.
In the figure, 1, a support plate; 2. supporting ribs; 3. a guide plate; 4. a hold-down bolt; 5. a fastening plate; 6. and (5) fastening the hole.
Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following descriptions.
Referring to fig. 1, an embodiment of the present invention provides a guide plate mounting structure for a slurry pump, including a supporting plate 1, a supporting rib 2 disposed on the supporting plate 1, and a guide plate 3 fixed on the supporting rib 2, where the guide plate 3 is arc-shaped, and an arc-shaped groove matched with the guide plate 3 is disposed on the supporting rib 2; the guide plate 3 and the support ribs 2 are fixed through the compression bolts 4, and the installation direction of the compression bolts 4 is perpendicular to the tangent plane direction of the guide plate 3.
The number of the hold-down bolts 4 is at least two, and the two hold-down bolts 4 are respectively arranged on two sides of the central axis of the guide plate 3 and symmetrically distributed along the central axis. Further, an included angle formed between the two compression bolts 4 is 60 degrees. The arrangement makes the stress distribution of the guide plate 3 and the support ribs 2 more uniform, and the structure can bear larger impact force.
The pressing bolt 4 comprises a large head part and a screw rod part with external threads, a countersunk hole used for clamping the large head part is formed in the guide plate 3, and a threaded hole matched with the screw rod part is formed in the support rib 2. During the assembly, clamp bolt 4 from top to bottom inclines and penetrates baffle 3, and screw section twists in the screw thread hole in the brace rod 2, and after screwing up completely, major part clamps spacing in the countersunk head on baffle 3 to realize the fastening of baffle 3 and brace rod 2.
In the existing fixing mode, a compression bolt 4 vertically penetrates between a guide plate 3 and a support rib 2, as shown in fig. 2, a fastening hole 6 is formed in the support rib 2, a fastening plate 5 is arranged in the fastening hole 6 and used for realizing locking in cooperation with a screw rod part of the compression bolt 4, when the slurry pump works, a cross head applies force in the vertical direction to a structure, the force is consistent with the fixing direction of the compression bolt 4, the compression bolt 4 is easy to loosen, the stability of the whole structure is influenced, and the service life is shortened.
And the utility model discloses a mode that penetrates 4 slopes of clamp bolt makes its installation direction perpendicular with the tangent plane of 3 should departments of baffle, has increased the laminating degree of 3 and the 2 contact surfaces of brace rod of baffle, makes the structure still can keep better fixed strength when receiving the power of vertical direction, reduces not hard up phenomenon to the life of extension equipment. The installation mode has reasonable stress distribution, does not need to additionally arrange a fastening hole 6 and a fastening plate 5 between the support ribs 2, and has simpler structural processing and lower cost.
The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
